MODE button stopped working after the first save on JJOS2XL

Hi everyone,

I got the JJOS2XL password today.
So I made and saved the project.
I rebooted the MPC to check if it's saved.
And then the [MODE] button doesn't work.

I returned to JJOS 3.13 [power button] + [tap temo] and nothing changed. Still not working.
What is that supposed to mean?
I think a 100% that it's because of JJOS

Please help me

I'd wager it has nothing to do with JJOS, and is more likely a bad tact switch. Take the top off, spray some deoxit in the switch... or get some new tact switches and solder a new one in place or get a buddy good with soldering to do it.
