DIY quantize grooves cause audio to move BEFORE bar.

Posted this in General but it’s more of an Issue:

I’d been having weird problems quantizing things in 9 and today I updated to 10 and am still noticing the same problems. I created a video:

Basically when I create a quantize setting and apply it to audio, whatever’s on the downbeat jumps back past the downbeat to the quantize setting BEFORE the bar. Very odd.

Even more odd: midi doesn’t appear to do this - it just stays put, on the downbeat.
