Featured Images Are Being Saved at a New Location ... and now they don't display

I'm having a problem with the way my featured images are displaying ... and I think it has something to do with their location.

Those that display properly have this url structure:

Those that don't, have this url structure:

Can anyone tell me what's going on here?
