MuseScore 2 - Hilarious dotted half note/dotted breve tremolo rendering graphical glitch

Currently running 2.3.2, and I'm witnessing something uncanny here. I'm currently transposing Elgar's Enigma Variations to a 9-trombone ensemble, and I put in some tremolo. All good, it's just tremolo, and it plays perfectly fine. I finish the variation and I move on to the next. I wake up the next morning only to find out that the tremolo just did something hilarious to itself. Time signature is in 3/4 throughout the whole variation, and the tremolo at the end, while intended to be dotted half notes, transformed into dotted double whole notes. I wonder... "does this still play correctly?" And it does; it's perfectly fine, plays like it should, but they're still dotted double whole notes! Makes no sense... it rendered completely differently than it should've (though, to be fair, dotted breves have 12 counts and dotted halves 3, so the easy divisibility could be a factor).

This glitch has happened repetitively after closing and opening several times, even when making minor changes to the piece. It can also be fixed equally as simply; just make some modification to the measure in which the tremolo lay, and undo it. Problem solved, that measure is absent of any sort of glitch. Only that measure, though.

My real problem lies not with this funny glitch, but in the fact that this glitch is present even when you export the file to PDF. If you don't fix the glitch, it remains as part of the PDF file. Fix it and it's gone. I'm surprised that this hasn't been posted here before...relatively simple to replicate, I would imagine. Check files in question for proof.
