Reply to TP2: Loop not aligned to the grid mark

Hello,
Using Traktor Pro 2 I am no longer able to get the loop automatically aligned to the nearest grid mark, by pressing any loop size button (2-4-8-16-32). Then the loop could be started anywhere between 2 grid marks and not perfectly aligned on a beat, making a very unpleasant loop effect.
I tried all the setting available, nothing fixed this ( I never got this issue with Traktor pro or Traktor S4). Very annoying as I can not trust the loop process anymore to do it on a live deck (need to first use the move-loop-fine option to aligne the loop to a grid mark). Anyone with a solution by any chance?
