Mod_Rewrite problem

For me this is hard to explain so I need to show you, Click on the link below:
Champions League - TxL Forums

This link is for the champions league and there are 4 groups, all have the same forum names but if I click on "Arrange a Match" in group B, C or D then it redirects me to Group A "Arrange a Match" since it is the first one on the list going in order.

I didn't wanna have to change it all but I thought there might have been another solution?

All forum names have to be unique, unless you include the forum ID in the URL format.

If you don't want to change your forum names, you will need to customize your Forum URL formats and add the forum ID.
