Recurrent items not deleted from the calendar

[caroltranslator]

Hi. I use this software mostly for the calendar sync. Since a recent reinstall, my many recurrent items keep reappearing every time I sync the calendar after I delete individual instances. In fact, all those recurrent items reappeared until forever in the past, too. I have several weekly recurrent items that I need to delete once completed without affecting future recurrences. Thanks!
