I have a tree called “Conger” and I put some of my wife’s ancestors in there, but they are not being recognized with the synchronization very well.
For instance, Juan Jose Fiero Ramirez in FamilySearch has a PID of KWFW-3DS in FamilySearch but when I try to synchronize him by choosing his profile it gives LRVB-SZY as a recommendation. LRVB-SZY is shown as living. As for some background, I had KWFW-3DS listed as living, then gave his death date and place and then tried synchronizing again and it still gave LRVB-SZY (living).
