Digitone II storing midi information

Hi all,
As anyone I store my projects. And I wonder why I lose the information on my configured midi channels. For example midi channel, all the midi cc assignments etc. Or the whole midi channel is all of the sudden a swarmer. Does this happen to other people as well. Or is it a glitch at my side. Could be doing something wrong.

Weirdly. Tried to reproduce and it seems to work. I reloaded the project and saw original MIDI channel information. But my question though… how did they disappear change in the first place…?
