Cant disable internal reverb. (Revx)

Hi,

Ive tried to trouble shoot this every single way and Im completely stumped.

I cannot for the life of me figure out how to turn off the internal reverb in the UR44. Im using Ableton 11 and Big Sur. Ive downloaded what I believe to be all the latest drivers. Ive tried to uninstall the effects, but that didnt seem to do it.

Why wont the blue REV-X button turn off? Ive clicked it a thousand times now. Nothing.

Ive tried to uninstall the effect Suite 3 times but it doesnt seem to affect anything.

Please help!!
