Bizarre Musescore 4 dynamics bug (Latest version)

Hello. I don't know if it's just me, but I've found a very strange bug within musescore 4. Dynamics placed in a section of music, or maybe just notating certain notes in a certain way, can alter/mess with dynamics and phrasing before the location of that dynamic. For example, if I shift or add dynamics to an instrument, or if I write new music after an already existing section, the music 10 bars before or at the very beginning of the piece may be glitched/bugged/different sounding. It's extremely bizarre and frustrating. Sometimes this issue is completely unfixable, and sometimes I need to adjust the dynamics of the instrument to fix it, which of course is not ideal. Advice and help would be appreciated. Thanks!

For some reason, the file upload tool wasn't working for me, so I uploaded an unlisted youtube video instead: https://youtube.com/shorts/-8JpfIO4IUg?feature=share

Yes, I have musescore 4 on the latest version.
