It would have to be coded specifically, as I assume it doesn't work for serialized arrays, if it does, then I have no idea why it doesn't work. But either way it isn't an eShop error as it was never designed to work for front end editors.
Thank you again elfin, yes it's not an error. I just would like you or any to please help me with instructions or a specific link on how to code those eshop metas to show up in the custom field
