Can't access the tuner/tools

Hi there, there’s some time that I can’t access my tools/tuner anymore, is there a way to fix that? I already tried to reset factory default but still can’t access it.

I used to have an issue with the left footswitch. Eventually I returned the unit for repair, and after the replacement, its been good. Don’t know if this is your issue …

Now that you’re saying, feels that the middle one is not working…
