I see Julie Ricketts helped you solve your issue... I now see two sons listed (whereas before, I could only see one)
Turns out your other son was indeed connected to a different mother (even though that "different mother" was also you).
Since you had two profiles for yourself, then "you" were not really "you". Now that your own "twin" profiles have been merged into one, you are you again. Whew, I bet you feel better now, not having a split personality anymore.
Every profile has a unique ID number, so you have to pay particular attention to those numbers.
