Changing zwave node name creates duplicates?

Hi
I managed to connect my Zwave after a couple of days trying.
I do have 108 Zwave fibaro switches and dimmers.
The problem is that after importing them from Zwave stick they are all having the same name.
I started to rename them but after restart i see that the ones with the new name are not active and there are new ones with tho old generic name.
So when i switch on the light than the icon with the generic name is changing and the renamed one are still off.
