Featured Image Field missing off of front end calendar form

This is not the first time this has happened to me.........

Today I was hosting a webinar about how to use my client''s webinar and one of the things I wanted to cover was adding an event to the calendar on the front end form. When I got there to show the webinar participants, the featured image field was gone. I was logged in as a *member* (Membership 2 pro).

As an admin, it shows up fine.

I do have a staging site set up..

I'm not sure what is happening. I did clear my site's cache as well as my browser cache.
