Default group

Options

We have groups which are all shared between Teamviewer users.

Everytime i install Teamviewer host (downloaded from Design & Deploy which has a default group selected) and after i assign it from the client the computer is added in a group named Unknown1. I created a new group and didn't share it, changed the default group in the Design & Deploy to the new one and then new clients gets added in this group succesfully. So how to add new computers automatically to a shared group after i assign them?
