Scheduler and Private mode

Firts of all confratulations for this great component for joomla.
I’m using actually joomla 2.5.4 and php 5.2.17.
I set the private extended mode on and created events with 2 different users. Then I tried to modify the other user event. I expected not to be able to do this, but i did. The system allowed me to change the event created by user1 while i was logged in as user2.

How can I fix it?

Regards.

Please confirm that you have both events after enabling “extended private mode”.
