settings from MS3 to MS4

When I open a file from MuseScore3 in MuseScore4, the original settings, like the panning and volume settings of each instrument part, are ignored. I have to mix them again, which gives me a lot of work.
Is there any way for me to preserve the original settings of my compositions created in Musescore 3?

Maybe this question has been posted before, but I couldn't find it.
