WS2012R2 and components backup not working

Hello,
I’ve a NAS with Urbackup Server docker
I’ve a physical WS2012R2 (DC) and inside a virtual WS2012R2 (SQL Server).
Image and files backup are working great (a little slow sometimes but working)
My problem is windows components are not backed up.
If i configure the backup on the server (default=1). It’s not working.
If i configure components backup on the client, it’s not working neither.
In fact, whatever i select in the list and validate with OK button, nothing is saved. If i reopen window, all is clear.
Is it possible to resolve this issue and how ?
thx
