Pattern Longer in Song Editor Than It is in Piano Roll

Having trouble with LMMS? Ask about it here.
Using 1.2.0-rc8. I was putting together a DnB track and laying some chords when I noticed this. I laid out the chords and in the piano roll I see that my pattern is only 8 measures long. However, when I look at the Pattern Editor, my pattern somehow gets this extra measure of silence added to it making it 9 measures long.

This doesn't happen a lot, but it's definitely something that I've noticed in earlier versions of LMMS too.
What i have found, is if your final note is even slightly over into the 9th bar, it displays long silence section in the song editor, check your placing of note.
You're right. I zoomed in to 400% and I could see it was just slightly over. No idea how I got it that way
