"im having the same type problem. I was once married to paul, but we divorced no kids. i dated a guy here at fort cambpell ky got pregnant we broke up and i had the baby. But when i put the baby in it files her father as paul. or if i put the father into it it says i was married to him as spouse 2. its annoying and i cant get anyone from family tree help line to help me out with this. I dont want to just settle with it being wrong."
There is a bug in the program [at least in FTM 2011 and 2012] in this area. It has beeen reported to the development group, but you might want to also report the problem you are also having [Note if you are really using FTM 2010 there will be no more updates to it, all updates will be to FTM 2012[
