grid adjust options grayed out on xdj rx2? cannot shift the grid

hi, i cant shift the grid on any of my tracks on my rx2. i click the rotary button til the grid box is lit up, but dialing does nothing, and when i hit menu, the reset/snap grid / shift grid are grayed out.

tracks are analyzed, but doesnt work on not analyzed tracks as well.

does this have to do with other options in the menu?  alo i cant seem to find a comprehensive manual that explains what all the fuctions do?
