I created a recurring event on Saturdays and it keeps disappearing from the Calendar for no reason... This has happened to me a dozen times and Skool support's only answer was that it must be due to the extension tool... I have also found that if I create an event and then modifiy it, the description takes the title and repeats it 100 times and the Skool link then stops working (saying a 404 error when you click on it).
