can't change color on widget sidebar - m18xr2

I swapped to my other R2 and the keyboard widget side bar on the left side i can't seem to change the color on it through the FX app - any tips? stuck on blue

 

did you try shutting down the laptop completely and hold the power button with the battery unplugged? maybe it bugged out somehow and needs a power drain to fix it. my r1 had some funky issue with that, also sometimes it doesnt like changing color via the FX tab, had to go into the tactx tab and change color there
