First, the sevenths at the end are sixteenth notes in Sibelius, not thirty-second notes the way they're entered in Notion.
Second, the triplets should enter the same way at the end of the measure as the do in the beginning. Are you entering them in chronological order? I know our triplet entry isn't perfect, but I can't think of any reason why the first ones enter correctly, and the last one doesn't.
Re: triplets... I entered them chronologically in a different bar and copied that bar to this bar. My first attempt was to do the triplets first and do the 32nd notes afterward, and it started messing up the triplets when I got to that 4th quaver of the first bar. If I recall correctly, the end result was about the same.
Okay, trying it again -- it seems the problem occurs if the page isn't wide enough to hold one bar. Even after I made the page wider in my first attempt, though, the problem persisted. If I make the page wide enough to begin with, it seems to work.
