Ubuntu 20.04 network profile issue

Hi friends, fresh installed Ubuntu bare metal 6xNICs machine, new network profile for any of the nics creates a new profile for ALL the nics. The problem is all the network settings are copied to all the nics. I mean when you have an ethernet card every interface has different network settings but here does not work in that way.

If i delete that profile in one of the nics, then it dissapears not only for that interface but for all interfaces.

No way to create a new profile only for one of the nics, the profile is created for all of them at the same time, and the network settings for that new profile is not only for one interface, it is copied to all nics. Is this a bug ?

I cant get it to run. several machines installed with Ubuntu 20.04 and the same happens to all.
