I tried something similar before, but it didnt work, I selected in the upper combo 'Froglet" and down there both 'Froglet' and 'Anti froglet'. But may be the problem was caused by other thing, I just deleted a tournament with same name before, may be it takes a while until it is confirmed so this way it was only revived with previous configuration.

Edit: I see I was wrong. It worked, so may be the problem was the first tourny wasnt deleted because one player joined already and I always just returned to the first undeleted one without seeing any change.
Or it wasn't deleted because there are four check boxes left to the delete button, and I never touched those before.

Fencer: yes, the override feature would be logical I think
