The date picker can't be closed and hides other areas like choosing attendees

Steps to reproduce

After opening the date picker, I can't close it and it hides some other areas. For instance, I can't choose the attendees as the date picker covers it. No matter where i click, it won't disappear.

Expected behaviour

The date picker can be closed.

Actual behaviour

The date picker can't be closed.
