Current Behavior

I’m trying to get a multiday calendar event to be split to show the event on each day of the calendar. Right now it only shows the event on the first day.

Expected behaviour

according to the docs the “showMultiDay” should split the event up and show it on each day. Or at least that’s the way I understand it.

I had stopped updating at v6.2.0 since I could never get it to look right.

this is what it looked like with that version:

I finally tried updating again to the latest version and this is what shows now:

notice the icons aren't spread across multiple days. Only the icon for the first day of the event is showing
