Issues with replay functionality when converting some mousescore3 files to mousescore4

Hi !

I have been using mousescore 4 for a while. I have upgraded many files from mousescore 3 to mousescore 4 without any problems. I still have some files with mousescore-3 format. When I try to upgrade mousescore-3 files that contain repeat characters, I have problems with the upgraded mousescore 4 file not taking the repeat characters into account. Why?
