Former champs winning world title after losing?

Love the game ladz. Have also since got the ringside addition… but still currently playing the normal one more often due to how far into it I am at the moment.

However, I have noticed with my fighters who’ve won world title(s) and then lost a fight… they drop ranking and I usually have to have around 5-7 fights to get another shot at a belt but pretty much every time a fighter gets a another title shot after losing it, they lose?? Is this purposely made like that or am doing something wrong? I understand age would play a factor but some of my guys are 27-30’s and it’s like they’re not able to win a WT again after being beat
