Error after disabling Xray 7.0.0 - duplicated associations between custom field

When the Xray 7.0.0 is disabled is showing duplicated associations between this custom field.

The client was unable to load the Custom Fields page in Jira.

When verifying the database, this custom field “com.xpadit.plugins.xray:test-pla-filter-custom-field”  has been duplicated by associations between this custom field and screen configuration.

The client followed the steps suggested in this KB article Duplicate key error in Jira server on creating issue via REST API or accessing Custom Fields page in JIRA to remove the duplicate. Once done, the client could see that the custom field page and screen configuration page load correctly.
