Group members

Hi,

i have following situation and don’t know what’s wrong.
We use Gitlab Community Version 14.3.2.

I have 3 private groups. Every group has members. For clarity we call them D,N,P.
My User is in group N with maintainer role.
Group D has group members group N and group P has group members group N with maintainer role. Both are not direct members.

If I want to fork a project from group D via the UI I can only use my own namespace and the namespace for group N but not for group P.

So what am I doing wrong? If I am a direct member of group P I can use this group to fork to.

Hopefully you can help me or give me a hint.

Cheers
Markus
