Music Playlist not playing from beginning when changing a state in Music Switch Container [완료]

Question

I have a music switch container which contains three playlists - A, B and C.

I've set up three states to switch between these.

When switching to B or C, the music segments starts from the entry cue as expected, but playlist A starts at a different point each time - it's as if the play cursor is jumping to an arbitrary point. (The timing of the transitions between the three states are working correctly/as expected).

I've taken a look and can't see where this anomaly is happening. The only difference between playlist A and the other two is that A contains several custom cues, as well as multiple tracks.

Can you point me in the right direction? Thanks
