Calendar sometimes does not take over event category (incl. color)

If you set a category for an event (incl. color) it is taken over in the edit field but not in the calendar view (tooltip shows category empty but in the edit window category is set ok)

There is setting for it: Tools - Settings - Calendar - General - Source of event’s color in multicalendar mode:
Hope it helps.

This is a sporadical (not a general) problem. It is solved (as a workaround) if the the values of the event are changed. Afterwards the category and the color is correctly taken over. I still thin this is a bug.

OK, we will investigate it further.
