Attaching filters to provisioning targets is broken. You can successfully delete them using the UI, but they are still used during processing. The only way to find that out is to add log lines and see the rules you deleted being used. Manually clearing the cm_co_provisioning_target_filters table is the only way to move forward.

Also GroupNameFilter is broken when trying to filter the CoGroupMember on the CoPerson: Error: [TypeError] Argument 1 passed to Hash::extract() must be of the type array, null given, called in /srv/comanage-registry/app/AvailablePlugin/GroupNameFilter/Model/GroupNameFilter.php on line 114
