Ambika : Corrupted display on MIDI note

Hello, I’m asking here because honestly, I have the weirdest issue I’ve seen so far.
It’s intermittent as it will not do it for 3-4 days straight and then do it for a week.
My display gets corrupted data (random characters) when receiving MIDI notes and changing menus. The rest of the synth works so I can blindly change the parameters and change the Menu page but the display will show garbled data.
The weird thing is : it only does that when MIDI is plugged in MIDI IN. One workaround I found so far is removing the MIDI cable, pressing Library a couple of times, and plug it back in.

Anybody ever encountered this issue or would know where to check?
