Custom form restriction not applying for content editors

Matrix Version: 6.58.0

Hi folks,

I’ve globally restricted ‘Custom forms’ from Content Editors using the Content Editor Feature Restrictions settings. No additional feature restrictions have been applied at the group or user level. However, Content Editors can still access and edit Custom forms. It doesn’t seem to be working. When I test with other asset types (e.g. Standard page), the restriction works correctly and the user is prevented from editing them. Is there a reason the restriction isn’t applying to Custom forms, or could I be overlooking something?

EDIT: The restrictions prevent me from creating a form but users can still edit them, so it half works. Same results when applying the restriction at a User Group level. Possibly a bug?

Thanks!
