Problems with MMM-CalendarExt2

[Vauxdvihl]

Hi friends,
among other modules i have running “MMM-CalendarExt2” and “MMM-CalendarExtPlan”.

The view from “MMM-CalendarExt2” looks like.

And the view from “MMM-CalendarExtPlan” looks like:

Sometimes CalExt2 shows all the infos from the connected calendars in the config (so same among like ExtPlan), but often it “only” shows a few entries.

Maybe somebody can help me?
Thanks a lot
