Occurs when using *Read Only, with Local Groups* or *Read/Write* LDAP Permissions in your directory connector.
This issue is caused by there being multiple groups in your external directory with the same name (could be different cases name).
If you want to use some of your groups then you must configure your Group Object Filter in the Group Schema Settings of your connector to not include the groups causing issues. Example:
