Well, it seems like its duplicate of #7060

Thanks for the report! We'll use this ticket to track the problem instead of #7060 because it has a good reduced test case.

Seems to only be an issue with the react connector

I would add that when switching views and back again (for me, in my situation), the issue goes away. Additionally, if the calendar is initially opened in a different view, the month view looks fine when selecting it.

Fixed in v6.0.1
