an user with limited rights, confirmed he can't do anything is displayed as an Full administrator.
The display is identical in dutch.

This is not a bug. The rights you have on the server and rights you have on a device group are two different things. You can have no rights to manage the server, but full administrative rights on all devices in a group.
I hope this makes sense. If there are improvements to the user interface to make this better, let me know.
oke, thats makes sence, but it would be more clear if you call it in full device group admin instead of full administrator.
Perhaps call it "Group Administrator"?
Published MeshCentral v0.4.6-u with this change. In this version, the user panel is upgraded quite a bit. You can now add/remove device groups and add/remove a user group membership. Note that user groups don't do anything right now.
fixed, hope there will be an expansion of the funtion "user groups" soon
