XDJ-RX2

Hi, I recently purchased the XDJ-RX2 and it seems to have an issue when queing tracks, it quite often doesn't let me que at a point I need, I'll hold the beat where required and do the usual start and cue, but when I hit que it jumps off the point slighlty... I mix quite fast and this is driving me nuts.. I thought it might of been because I needed to do the firmware update, updated the firmware and nothing has changed. Please let me know what's going on? Thank you
