Trying to sell on Amazon- won't let me sell

[flibbage0]

Trying to sell my first product on Amazon and everything but when it comes to adding to the catalogue it says that my listing is incomplete and that additional information is required, however nothing is highlighted. It just keeps saving it as a draft

I've tried removing watermarks, giving a simple title, changing the category. Even tried contacting Amazon support and they've completely ignored me.

Any advice would be appreciated
