Library Hot Cue "E" (rekordbox 6, Opus Quad Library)

Hello,

I bought an OPUS QUAD, moved from rekordbox 5 to 6 and activated both libraries (CDJ + Opus Quad).

A lot of tracks, which used to have hot cues, do have an "master" Hot Cue on "E". This looks like a bug to me, because it overrules all existing ones and also when e.g. changing the loop size the track moves from my current position / cue to the faulty "E". 

It would be ok to erase all hot cues and start from scratch, but those hot cues on position "E" always come back. This is very bad when playing live and loosing control :)
