relates to #270643: [EPIC] MusicXML import/export issues

I have written a piano piece in Staffpad and there are some measures with 2 voices in both hands. I exported the file in MusicXML in order to finalize the score in MuseScore. I attached both staffpad MusicXML and Staffpad file (in .zip) and uncompressed MusicXML from MuseScore (after I corrected the score manually with reentering the notes and change the voice in left hand staff).

Open MusicXML from Staffpad in MuseScore.
See at bar 9, 11, 12, 15, 16. The left hand is messed.

These are measures where there is voice 1 and 2 in right hand and voice 1 and 2 in left hand. I edited it like this in Staffpad. In MS I see that there is voice 1 in right hand and voice 1, 2, 3 in left hand. Left hand's voice 1 is in the right hand's staff. Originally left hand's voice 1 and 2 became voice 2 and 3. And originally voice 2 in right hand became voice 1 in left hand.

I corrected the file in MuseScore and exported the uncompressed XML with Staffpad XML and there were differences in the voice tags. Staffpad opened correctly the MuseScore XML but if I exported again from Staffpad without any change, the score in Musescore messed up again.
