Layout of parts change after close and open Musescore 4

I'm migrating the scores from version 3 of Musescore to version 4.
After properly arranging all the parts, when I exit Musescore 4 and open that score, all the parts have different layout.
I go back to arrange again, record and leave.
When I open that score, the layout have changed again.
The first picture is the layout as I want and arranged.
The second piture is how Musescore 4 open after I leave and open again.
