CalDav in OH2

Hi,
I guess I read all the posts, discussions and article I found on google and tried all the solutions but but my items are still “UNDEF”. I have the latest versions of OpenHab (2.4.0-1) and the Binding (1.13.0) available.
Yes, I tried the solutions with and without the prefix in the configs in /etc/openhab2/services. Yes, I deleted the configs from /var/lib/openhab2/config/org/openhab
The .ical-files are properly downloaded form my Owncloud-Calendar, so I guess the caldavio.cfg is fine. But the items are not update.

My latest version:
caldavio.cfg

Hi,
my calender called Muell. And it works fine

String      CalDav_Muelltonne       "Leerung von [%s]"                          <calendar>      { caldavPersonal="calendar:Muell type:EVENT  eventNr:1 value:NAME" }
DateTime    CalDav_MuellDate        "Datum der Abholung [%1$td.%1$tm.%1$tY]"    <calendar>      { caldavPersonal="calendar:Muell type:EVENT  eventNr:1 value:START" }
