Field “Content Type” was changed and can no longer be selected

[paperandwax]

In my base, I changed content type to multiple sections from single and now when I try to view the calendar view, "content pieces" it gives me a "Field “Content Type” was changed and can no longer be selected" 

Any suggestions on how to remedy this? Thank you.

Hmm this is the error message I see:

How is that field used in the Calendar view?  If you could DM me an invite link to your base I'd be happy to take a look at it for you.  Tried to recreate the issue but wasn't able to I'm afraid, sorry!

I created a new base from scratch that is working and better. It was the easier solution than trying to dissect this one. Thank you!
