Expand and compress groups in elements does not work

[Natalie256998419jus]

Hello,

I'm just starting with Adobe XD so a little help would be much appreciated. 
I created some components and grouped them. But I cannot compress or expand the groups. When I click on the icon left of the group, nothing happens.

Could you kindly advise what could be the reason?
Best regards, Natalie

Has been solved:
I also had trouble initializing CC libraries. Since I solved that, it also works to epand and compress the groups in document elements.
