Fibaro Dimmer 2 - settings crashes app

I have a weird issue with 1 of my Dimmer 2-modules. I have 6 in total, the other 5 have no problem.

When I try to disable the ‘Double click’ function, I get this error:

And when I try to disable the dim-function, the Homey-app just completely crashes! :open_mouth:

Anybody having this also?
