You have the record trig and the playback trig on the same step? I think that I remember reading somewhere that in that case the sample trig will actually try to play the sample before it is recorded, which sounds like what you are seeing. You might try using micro timing the trigs so that the record trig happens just before the sample (playback) trig.
This thread also suggested using QPL, but I’m not sure I have wrapped my brain around that one yet.
