When I try to add a description to an event, it is not saved. It just isn't there. This happens even after saving the event and saving the calendar. The month with my first event doesn't have this bug, and the vignette box appears differently: On the bugged months, the box, on each line, has a plus sign for different types of text and six dots to rearrange the lines. On the working month, it is just a text box.
The calendar.
