Admin group not visible in list of groups

Logged in as admin user If I create a new group folder I cannot see the admin group in the list of groups applicable for the new folder (NC 25, Group Folders 13.1.0). Did anyone experience this problem?

I have the same problem since the last update of group folder.

I have the same problem in version 25.0.1 Group Folders 13.1.0

I have the same problem : NC version 25.0.2 and Group Folders 13.1.0
