A little help required :-)

I have created show rules to play a category of music by style.  Upon scheduling it looks and plays fine.  The issue that I have is that a cart from the Audiowall is being manually inserted in to that show's log in Q-Nxt just after a jingle.  In "Preview Auto" mode the manually inserted track plays after the jingle but in 'Auto Fade On Air' mode it is being 'dropped/deleted'.  As the track is not scheduled by Auto-track but manually inserted I don't have the reason why.

Please can someone point me in the right direction for checking scheduling in the correct order.  What am I missing?
