Reply to Weird probleme with the auto grid

Hi when i set my autogrid, it usually works, but sometimes when i load a track:
-> The grid is all wrong (it's not on the beats) (and that can happen with a track that i've already prepared or a new track)
-> The Cue points are not xhere i put them
-> I have to reload the track in order to have the normal grid and cues

How to fix this issue ?
