Support says that it worked as intended.
It's funny that everyone we showed the feature to didn't understand why it was displayed like this.
the fact is, everything is correct in the port details, it's only in the "switchports" dashboard that it's wrong for me.
Who cares about the "original" VLAN, we want to see the configured and active VLAN! Likewise, if I remove a port profile, it is still displayed. The only workaround is to create a profile with the name "-".
I have marked this in orange.
The feature itself is great, if it weren't for these two details.
