So if you turn EA off and commit, the audio moves on the track? I've never seen that here. Say I move some warp markers to a grid line and commit. The audio stays ion the grid here. Routing or bouncing to a new track can net some audio offset for a few reasons;
A bug in PT(seen this myself)
Latency caused by plugins(especially on the master track)
Latency caused by a large buffer setting(which PT should compensate for).
These reasons are why I generally just turn EA off and commit where it is
