How can I delete an invite from Tournament?

I firstly invented players I know. Then I play with the most. But few only accept. Then I tried randomly few players and I didn't full the list

My problem is some of these player I know, I spoke to them about the Tournament but they keep silent and say they invited there friends. The real problem they don't accept or declined and now the list is full as I also try to invite some in the day after hoping some join or declined. I need to remove some but don't know how.

How to remove an invite from the list?

You can't, sorry :)

You can write "Those who don't join, decline" and hope those see and decline the tournament.
