Edge keys won't light up after move button pressed

[zass30]

Press the <MOV button once, and then press the upper rightmost key on the Linn (F). That key won't light up on the midmech UI. Neither will any key in the rightmost columen. If you press <MOV again, then no key in the two rightmost columns will light up, etc.

Same issue on the left if you press MOV>
