Can't configure NUT

Just installed OMV and am trying to get NUT up and running. Can't seem to get to work. I keep getting the following error message whenever I try to save the configuration:
"upsname: The value 'ups' doesn't match the pattern '^[a-z0-9_-]+$'."

I've tried everything I can think of but nothing worked. Searched the internet for a solution but nothing comes up. Can some help me with this? What am I missing?

I left the name as "ups"

the driver = usbhid-ups
and port = set to auto

Thank-you for your help, updating all the packages has fixed the problem. don't know which one did it as I updated them all. Again thanks for your help.
