# Datastore Quality Score Troubleshooting

*Requires the Data Observability (DO) module.*

This page documents common quality score problems and the steps to resolve them. Each section describes a symptom, its cause, and the resolution.

## Missing Scores

### The Datastore Has No Quality Score

A datastore shows no quality score on the Datastores listing page or its Overview tab.

**Cause:** None of its containers has a score yet, or the datastore is an enrichment datastore. Datastore-level quality scores are offered only for source datastores.

**Resolution:** For a source datastore, run **Sync**, then **Profile**, then **Scan** on the tables you want to monitor. Enrichment datastores do not get a datastore quality score.

### A Container Shows `-` Instead of a Score

A table or file displays `-` where its quality score should be.

**Cause:** A container receives a score only after it has a completed profile and a completed scan. Containers showing `-` are excluded from the datastore score, so they do not pull it down.

**Resolution:** Run a Profile and a Scan that include the container. See [Which Containers Get a Score?](https://userguide.qualytics.io/source-datastore/data-quality-score/deep-dive/calculation/container-level-scoring/#which-containers-get-a-score).

## Unexpected Values

### The Datastore Score Is Much Lower Than Expected

The datastore score is far below the scores of the tables you monitor.

**Cause:** Tables that were profiled and scanned but have no checks receive very low scores, and every scored table counts in the datastore average. This usually follows a datastore-wide Profile and Scan during setup.

**Resolution:** Run operations only on the tables you intend to monitor, or use tag weights so those tables dominate the average. See the [low datastore score example](https://userguide.qualytics.io/source-datastore/data-quality-score/deep-dive/examples/) for every option.

### The Score Does Not Improve After Fixing the Data

You fixed the source data, but the score stays the same.

**Cause:** Qualytics does not know the data is fixed until a scan confirms it, and old anomalies count until they leave the decay window. Another dimension, or a dimension with a high weight, may also be holding the score down.

**Resolution:**

1. Run a Scan so the anomalies are re-evaluated.
2. Open the dimension breakdown on the container detail page and look for the dimensions that still score low.
3. Review the [dimension weights](https://userguide.qualytics.io/source-datastore/data-quality-score/how-tos/quality-score-settings/) for a dimension that dominates the score.

### Coverage Keeps Dropping

The Coverage dimension of a container goes down over time even though no checks were removed.

**Cause:** Coverage rewards checks that scans assert often and recently. Checks left out of your scans, for example when scans assert only [selected checks](https://userguide.qualytics.io/operations/scan/how-tos/select-check-categories/), count less as time passes.

**Resolution:** Pair targeted scans with a regular scan of all active checks.

## Settings and Tags

### A Settings Change Did Not Change the Score

You changed the decay period or dimension weights, but the displayed score is the same.

**Cause:** Settings changes apply to new scores only. Already-recorded scores keep the settings that were in effect when they were measured.

**Resolution:** Wait for the next scan, profile, or other event that recalculates the score. See [What Triggers a Recalculation?](https://userguide.qualytics.io/source-datastore/data-quality-score/deep-dive/how-it-works/#what-triggers-a-recalculation).

### Tagging a Container Did Not Change Its Weight

You added a weighted tag to a container, but the datastore score did not shift.

**Cause:** Container weights are recalculated only when tags are added to or removed from the **datastore**, or when you use **Move to**, **Merge**, or **Remove** on a tag's page. A tag assigned directly to a container does not change its weight until one of those happens.

**Resolution:** Change the datastore's tags, or use one of those actions on the tag's page, to recalculate the weights. See [Tag Weight Modifiers](https://userguide.qualytics.io/source-datastore/data-quality-score/deep-dive/calculation/score-settings/#tag-weight-modifiers).

## AI Explanations

### The Sparkle Icon and AI Explanations Are Missing

The Quality Score panel opens without the AI summary, and no sparkle icon appears next to the score.

**Cause:** AgentQ is not configured for the deployment. Without it, the panel shows the score, dimensions, and static descriptions, but none of the AI-written content.

**Resolution:** Ask a user who can manage integrations to configure AgentQ. See [When AgentQ is not configured](https://userguide.qualytics.io/source-datastore/data-quality-score/deep-dive/interpretation/ai-explanations/#when-agentq-is-not-configured).
