BUG - Slip Loop becomes Hot Cue

I've been having this bug recur frequently and I always wondered what it was.

When I'm using the SLIP LOOP feature, usually it works, but after a while, sometimes it actually functions as HOT CUE.  So, pressing a slip loop could jump to another point in the song, completely ruining the mix!!

I'm not sure exactly how this occurs yet, but it has been doing so after >30min of use.  XDJ-RX2 With latest firmware updates, regular USB mode (not controller).  Has anyone else had this problem?
