Not working with configuration reference

I have a configuration reference, so there is a taxonomy with a field "content type" which references to any number of content types.

Only if I enter > 1 content type as reference I get an error message

Drupal\Core\Entity\EntityStorageException SQLSTATE[23000]: entity_usage Integrity constraint violation: 1062 Duplicate entry for key 'PRIMARY': INSERT INTO {entity_usage}

Probably Entity Usage must exclude saving data on Entity References to configurations to avoid this since they donnot have an unique target id.
