Group delete issue

Hello,
after importing AD groups. I find that the groups display and very slow in pydio. I also note that I can not delete groups in pydio by selecting them. I have to do it one by one which triggers it on my browser:


Someone can help me
thank you

Mapping AD groups to Group Path is deprecated. We recommend to use mapping to Role ID.
Pydio will connect to ldap and construct a list of users/groups/roles “on-the-fly” so you can’t delete mapped groups/roles in Pydio. Try to delete by modifing ldap filter in Ldap config.

I Try to delete by modifing ldap filter in Ldap config. But mapped groups are still here.
Maybe you are somebody else have an other advice for me ?
