Group Admin cannot create group

Hi sorry new here I have a small problem. I have successfully install nextcloud 14.0.4 on an Ubuntu 18.04 server. I already created some users and groups. I also assigned a user to a group and gave it group admin. Now when I use that user to login I can create users no problem but I cannot create new groups. Please help

Please anyone have any idea how to fix this?

Is there a solution to this issue? When my group admins try to create a group, error returned is that group can only be created by an administrator.

In NC 12 this was possible.
