UPS Slave Driver Error

Anyone have this error? I previously had truenas setup as the master, but switching it over to OPNsense.
Truenas can query OPNsense but I can’t save the config because of the driver, even though it doesn’t need the driver for this situation. Does anyone know how to clear this out?

TrueNAS-24.10.2.2

after trying a million things, the fix was selecting a different driver from master, saving…then going back and editing it to slave, and it will then let you save the config
