Filtering automatically generated categories in the Wix App Categories Collection

Question:
When I add a category for an event, records like comp-m3og19y9 are automatically generated. Although they have the Hidden tag, they still appear in the results when I search the Wix App Categories Collection. Is there a way to filter these records out? They appear when I create a dropdown list based on Categories which is not ideal.
