KNX ETS6: GA linked hierarchy in Topology view?

I’m sure other wonder a lot ETS6 like me so I try to ask these questions any maybe help others later.

I’ve some devices linked with Group Addresses in Topologoy view. One of that has problems, has Linked with column with hierarchy, there are room, description and the GA-description. This one doesn’t work, but I’m not sure yet why.

I have other same devices and they work, but they don’t have that hierarchy. Both have physical location in project root hierarchy set so I’d assume that it would create that hierarchy to all, but it doesn’t.

This one is the most distant one so it could be cause by RF-issues with weak signal. I’m able to Download to it anyway.

Any idea where that hierarchy part comes from?

Found it, I had dragged the GA into Buildings hiearchy, but did not do for all groups yet. Not sure what is the benefit of doing so.
