TWO audible outputs from each table - so if I mix across fully right I get both

Since I upgraded my Mac oSX DJay won’t work with Nicecast - it plays TWO audible outputs son the active table - so when I fade to table 2 and play there’s two slightly out of sync sounds from table 2 and still ONE playing on Table 1 that’s fully audible.

In other word the mixer crossfade takes care of ONE of the audible outputs but not the mystery 2nd one!

HELP _ had to cancel a show due to this.

So it appears to be the pre-cueing = when I started DJay it detected a new audio something and selected it for pre-cueing - I can’t find any way to set it back to what it was before
