Reply to Novation Dicer (DJTT mapping)

Hello all I have a question on the novation dicers I have them hooked up to my TSP and all function work great, with one exception the echo freeze effect works perfect on the left deck and but when used with the right deck it applies the effect on both decks?

Is this because there is only 1 USB cord? Will I need a 2nd one to get the effect to be applied to just the right deck itself?
