Cross staff beaming in score is completely broken following a corruption.

Recently I have been working on a score with multiple parts, which I have never done before, thus I decided to go part by part but made an exception to certain measures that I deemed important (those that were referenced in other part scores on the imslp source material.) However, there was a corruption in measure 124 based on all of the parts simultaneously recognizing an incorrect time signature. I eventually fixed this by deleting the measure and replacing its contents manually (which allowed it to save), however now I find that all the cross staff beaming I had previously inserted has been undone, and attempting to re-add it with the ctrl-shift-up/ctrl-shift-down shortcut results in unexpected behavior. Closing and reopening has thus far not been able to fix the issue, and it is happening score-wide.
As an example (this problem happens wherever there are sections of long beamed 32nd notes)
Expected behavior:
