Problem with dynamics not appearing on parts

Hi,

Musescore just upgraded me to version 4.2 and I'm now having issues with dynamics disappearing from my parts. I'm doing a Brass Band arrangement and nearly everywhere on the score where I have a hairpin crescendo or diminuendo they are missing on the part. Also trills are missing and there may be other things I haven't noticed yet. I don't think this was happening with the previous version 4.1, but I can't seem to find that version of musescore to install so I can't check.

I can manually replace them but there are a lot!

Is there anything I can do, or can I roll back to version 4.1 somehow and see if it's ok on that version?

Thanks,

Sam.
