Nuendo 8- recording/playback issue

I hope someone can help me! I imported a wave file of music to sing to and put it on it’s own track… But for some reason its being recorded onto my vocal track.Somehow it’s being recorded and the vocals and music are being mixed together as one. This is the first time in 13 years I’ve experienced this! Thank u in advance! Mike

Pretty hard to help if we know nothing about your routing or setup or anything…

I mean… check your routing?
