MIDI sixteenth note triplets imported improperly

[PlainSite]

Issue type

Import/export issue

Description with steps to reproduce

When I import this MIDI file containing sixteenth note triplets, only some bars are properly rendered as triplets. Others are converted to sixteenth note-thirty-second-note-sixteenth note pairs, and some are part of septuplets. There is nothing wrong with the MIDI file to the best of my knowledge.

I was unable to check

Operating system

Additional context

Cakewalk Express re-opens the same MIDI file and renders the notes properly. The time signature is 3/4, nothing crazy.
