It's right in the manual.... Section 9.2 - Snapping and quantizing Loops, Locators and Cue Points.
BTW, it's not uncommon to see this sort of behavior in other DVS software.

From the manual:
With the beatgrid feature loops, locators, and cue points can be set either at the current playback position or they can automatically snap to the next beat, next 1/2 beat, next 1/4 beat or next 1/8 beat of the tracks’ beatgrid. The snap on/off settings and the snap value settings are global parameters that can be configured in the Snap section of the Sync zone. If the Sync zone is not visible, open the View menu and select Sync Zone.
And when you change the beat grid to the way it should be it lands where you want it.

It all works together as a bit happy system.
