Schedule match problem

[pollyste77]

I modify in setting_modules.php scheduler in true.
So i found a new schedule interface to organize a tournament.
Also i translated in italian translations.xml related.
But when i search to choose two teams for a match, it returns this message without i can choose teams:
Finale - Orcacci vs. Orcacci - Illegal match-up, the passed team IDs are identical.
