All vacant world titles

I’m now over 250 fights into the game and I have a number of fighters in or around ranking positions for a world title shot. However, every single world title is vacant and I can’t seem to get a shot at this, even when matching against an opponent also in an appropriate ranking.

I saw someone else said this recently and the advice seemed to be to start again. Obviously I don’t want to do that when I am so far in to the game so is there a fix for this that anyone is aware of?

Hopefully we have sorted this out for you:)
