Sim Fu Lie, Please help!

Recently, I had my 2 sims spar 5 times. One is a female who used to beat up all mummies in tombs. Her traits are disciplined, athletic, brave, hotheaded and party animal. The other one is a male and traits are athletic, brave, genius, adventurous and virtuoso. This man completed sim fu king and grand master title in skill journal. The female one has only grand master title. I had them fight 5 times and the male won all the time. She doesn't like him any more. LOL
The different thing is that the male guy got trained from his daddy sim who completed all titles in martial arts skill journal. He learned martial arts from having spars with his grand master daddy. He raised up the martial arts skill from 2 to 8 in A Day while sparring with his daddy. I got surprised. So this guy got lost a couple of times in tournament while challenging grand master in China although he didn't have disciplined trait.
