Daddy's Girl<br>I was always a daddy's girl. One day he began calling me his princess. I became obsessed with princess themes. We decorated my bedroom with crowns and Disney toys. He told me I would always be his princess.
My father has no daughters.  
The paragraph is written from the perspective of "Daddy's girl" which means Daddy has a daughter.  Therefore, it is definitely incorrect to state that Daddy has no daughters.  The system got confused by the use of the word "daughter".  It likely does not know what the reference to Daddy's girl means.
