I think I found an SQL related Bug in Veeam B&R 9.

Looks like Veeam does not like the "&" in the "Windows Server" description field...
If i use a description with & (like Veeam B&R

After that, there is no way to close the "Edit Windows Server" window.
Looks like Veeam B&R 8 does not have this issue btw.
Happy fixing
