pROBLEM WITH mUSESCORE 4.3.2

so everything Sound wise with the new version 4.3.2 has been fine..the virtual instrument sounds are more nautural ..the idiomatic nuances are more present..there are some glitches that occur as the score is playing at certain places as it plays..but the sounds are quite an improvement from the version I had which was 3.3 or something around there...But now today when I am listening back on this particular score..the sounds are like some early version years ago..as the score plays ..everything is choppy ..even though I have added articulations ,phrase markings ,dynamics..It is painful to listen to...I still have the Muse Score 3 And tried copying and pasting a bit of this recent score but it wouldnt let me..and I have checked back through all my recently edited scores when I got the new version and all of them have been affected by whatever has happened between last night and today..so don't know..I shall include this latest one...as example..luckily I did make an mp3 copy last evening so that I have some example of how it has been sounding ..up until this point and all the other scores have mp3s with the update as well.. wellI wanted to add the mp3 file in this email but only one is allowed..
