Glitchy dynamic issues

Hi, I normally don't do this, but I'm at my wit's end here.

I recently had to switch computers, and when copying all of my MuseScore files over, I've been losing quite a bit in translation in my new files. This last one has been quite frustrating. Attached below is an example. In the cello at m. 10, I have two issues: 1) the PPP dynamic is not working at all. PP is working, and PPPP is working, but not PPP. 2) The crescendo that occurs in m. 13 has also not been working, despite me trying desperately to fix it. I've tried switching from CC 2 to CC 11, and that one is still having issues. What is really strange is that in mm. 18-19, the single-note dynamics are working just fine.

Thanks!
