If I add a new Calender, the new Calender is not always showen right a way. Sometimes I have to add another Calender, after that the Calender from the try before is shown, the other one sometimes, sometimes not and I have to add one more. Also the button for list permanently is sometimes activated right away, sometimes not.
Steps to reproduce:
1. Add new Calender 1
2. Add new Calender 2
3. Add new Calender 3
Actual results: After step 1 nothing happens. After step 2 Calender 1 appears (list permanently not activated). After step 3 Calender 2 (list permanently not activated) and Calender 3 (list permanently activated) appear.
Expected results: The Calenders appear right after they have been added and list permanently is activated.
