Views show fields is set, but only "Content" options are available to select - why? Simple question. I thought I knew views, but right now I'm stuck. All I want is a view with the body field of a certain content type.

I have "Fields" selected:



But when I go to add a field, my options are severely limited:



(There is no such thing as a "Content: Body" option to select.)

What happened to the rest of the categories in the Filter dropdown? I'm missing something obvious here...?
The Content: Body field should be there as long as it exists in the content type.  

A couple things you can try in this order:


Ensure all permissions are set properly
Flush all caches
Flush the views cache at /admin/structure/views/settings/advanced
Disable views cache just to see if that's an issue
Update Views


Here's a current issue of the problem
