Can’t add something to my exclusions list no matter what I try.

[Dbproxy]

I recently started playing BDO (Black Desert Online) and no matter how I go about it when I right click on f.lux then disable my options are “for fullscreen app” and “when using Search application”.
I've tried alt tabbing, hitting the Windows key, playing in windowed mode and moving my mouse directly from the game to the f.lux icon, I always get the same result.

Any help would be greatly appreciated.
