Reply to Traktor SYNC - Why does this happen?

So basically, I have been playing with 4 decks and sync lately. I never used sync before so I am a bit "noob" on that area.

I already learned (thank u youtube!) to beatgrid all my tracks, and I've done my entire library.



However, I am facing a problem. Let's say, Deck A is playing, I press sync and then Play Deck B and transition.

When I finish with Deck A (i mean, volume fader all the way down) I have the tendency to press CUE on that deck to return to my cue point.


However, if I have sync turned on in the other deck, the sound glitches like for 1 second. Why does this happen?
