You appear to be posting about an issue with Family Tree Maker software, and that is where your post is located.
You mention "AFT" which is something entirely different. I don't think "Ancestry Family Tree" software exists any longer. If you mean "AMT" - or Ancestry Member Tree - that is the online tree product from ancestry.com which syncs with FTM 2012.
If you are talking about problems with FTM, do you regularly compact your database? That process, especially when done frequently and multiple times, will often clean up issues.
