I imported that track 4 times - and after some working in the project (only tried out some reverbs in other audio busses) it plays wrong. I edited nothing in this bass track except the volume.
just a guess: is that bass riff for the intro of the song? maybe it is (audibly) starting from the very beginning of the midi file, instead of the playhead location.
Knowing where that riff exists in the track would tell us the ‘offset’ from the playhead, and that might provide a clue to what’s gone wrong.
I loaded your midi into my ardour 7.2 on Windows, and it was not right (as on your video) but… I changed the length of these problematic notes in way that their end does not overlap on next note (I did “un-legato”) and it solved this inconsistency
