Scratching my head with this. I am working with a custom block and have added an image field. However the Upload destination radios are not present and this results in a file storage error. ' Illegal choice public in Upload destination element'
Two screenshots attached. The first indicates what I am seeing, the second (from a different site) is how it should look.
I am only seeing this problem with custom blocks and find that regular content types are okay. Not just with image storage; files too.
