Tajima TMCE - 601 Chenille Machine ?

I'm making up some chenille patches for letterman jackets and I keep running into a problem. I set the machine up to do a navy loop stitch(D) first and then a white chain stitch(B). It starts with a white chain stitch and then does the navy loop stitch. Sometimes it'll even skip to a color that wasn't even selected. Has anyone had this happen before?

Thanks
