Reply to Off-Tempo Delay Effect Issue

The Delay effect is perfectly in sync when activated on my right deck, but for some reason it is slightly off beat when I activate it on my left deck. I use TSP2 with an S4 and Stanton ST150s, so I thought maybe it was just discrepancy caused by timecode, but the delay in the delay (wow I said that) seems to be the same every time on my left deck. Does anyone have any insight on what might be happening?
