How to view field name after changing Field Header on form?

I’m finding it frustrating that if a field has been added to a form and then the Field Header (display name) of that field changed, I don’t see a way to view which field that space on the form is linked back to.

As an example, on one of my forms I inserted “Account” but change the field header to read “Organization Name.” However, nowhere on the form builder UI does it say what the original name was. I do see Account greyed out on the Fields list, but that requires me to infer which field header that became.

Am I missing something? Or is this a missing functionality in the form builder?
