Syncronising datas, calendars und addresses

After I began to use Nextcloud I imported my calendars and adresses. Than I created in KDEPIM a new calendar an addressbook using carddav and caldav. After this all my imported Datas are shown but not the new one.
The problem is: New datas I created on the desktop in calender and adresses are not syncd to the cloud. The invers way is the same.
Also the desktop app do not syncronise from the desktop folder to the cloud.

Max be there is a tiny screw to change this, but I didn’t find it.

After I use ncp on my Raspi, the problem didn’t happen annymore.
