Strange midi problem with mpc 60 vimana

Hi, guys !
I'm trying to configure the midi notes on the pads of my mpc 60MKI with vimana os. the problem is that: when I save the program all the midi notes I assigned on the pads are saved correctly except for the PAD 4 on which I would assign the note 63 but strangely when I load the program we find the note 48.
I tried and tried again but there is nothing that works.

I have that same problem with Pad 4! I've saved the Program and Params over and over.
Midi Assign has a "-" instead of a 04 on the Pad number, I need to change it, then hit pad4 and change the note value. Mine defaults to 82?
Might be a low or dead internal battery? The Params should save all settings on power down, but it's weird how the Params and Programs load with Pad 4 skipping setup?
Any other reports of this, or solutions appreciated!
