Need to insert a short audio clip

I need to drop a number of short audio cuts into a presentation and use ducking to reduce the music track during the cuts and only during the cuts. No problem with all if that. But, FotoMagico see my cuts as insufficient in length and sends a big red-hatched error track shooting—over the top of other narration cuts–down the timeline. (One track music, one track audio) Every time I pull it back it snaps forward again. This messes up my other tracks but also negates my ducking. I know I want a 23 second narration cut but FotoMagio doesn’t believe it and is telling me my cut is too short. And the worst, this does not happen every time I insert a narrative cut. Suggestions?
