Moving Calendar items in other folders not working (New Outlook interface for Mac)

Hi, I have created several calendar folders within my account. All incoming appointments are shown in the standard calendar and there is no option to choose, in which calendar folder these meetings are being stored. Moving items (bith own and invites) to another calendar folder is also not possible.

Is this a known issue?
Thx, Nina
