MPC Live II Standalone --- MIDI-Ports lost

Hello,

I have the following problem:
I arrange my stuff on a MPC Live II using the MPC Software on Apple Mac M2.

I control several MIDI devices (I'm a keyboardist) via a MIO XL patchbay. My goal is to prepare for a live gig. This works perfectly with the MPC software (Fig. 1). https://hidrive.ionos.com/lnk/RAcu5p55w

So, I save my file (Fig. 2), https://hidrive.ionos.com/lnk/VNGV5boaH

close the software, and open the file on the MPC standalone. The MIDI ports are recognized correctly both in the software (Fig. 3) https://hidrive.ionos.com/lnk/V6c4NLxDi

and in standalone mode (Fig. 6). https://hidrive.ionos.com/lnk/NaN56mRvJ

When I open the file in standalone mode, the following happens first: The file is renamed and given the extension "_import" (Fig. 4). https://hidrive.ionos.com/lnk/FwgDBPtGT

Of course, I don't want that at all. Then the MIDI ports and channels assigned in the software are missing (Fig. 5). https://hidrive.ionos.com/lnk/BUC9S5f2o

Does anyone know this problem? Thanks in advance!

The "_import" postfix is added because the software runs MPC2 OS while the standalone runs MPC3 OS, and the conversion process names it that way. It also seems that the MIDI track settings, both port and channel, are reset during the conversion.
