# Troubleshooting cluster comparisons {#troubleshooting-cluster-comparisons}

When using the `cluster-compare` plugin, you might see unexpected results, such as false positives or conflicts when multiple cluster custom resources (CRs) exist.

## Troubleshooting false positives for missing resources {#troubleshooting-cc-false-positives_troubleshooting-cluster-comparisons}

The plugin might report a missing resource even though the cluster custom resource (CR) is present in the cluster.

**Procedure**

1. Ensure you are using the latest version of the `cluster-compare` plugin. For more information, see "Installing the cluster-compare plugin".
2. Ensure you are using the most up-to-date version of the reference configuration.
3. Ensure that template has the same `apiVersion`, `kind`, `name`, and `namespace` fields as the cluster CR.

## Troubleshooting multiple template matches for the same CR {#troubleshooting-cc-multiple-matches_troubleshooting-cluster-comparisons}

In some cases, more than one cluster CR can match a template because they feature the same `apiVersion`, `namespace`, and `kind`. The plugin’s default matching compares the CR that features the least differences.

You can optionally configure your reference configuration to avoid this situation.

**Procedure**

1. Ensure the templates feature distinct `apiVersion`, `namespace`, and `kind` values to ensure no duplicate template matching.
2. Use a user configuration file to manually match a template to a CR. For more information, see "Configuring manual matching between CRs and templates".
