WooCommerce options not showing

Hi

Im having some really annoying issues with WooCommerce. It is more than likely a mistake on my behalf, but it is driving me nuts! lol

I am trying to set up a variable product for a photo. An attribute for media type has been set up and another for sizes.

These have all been linked and setup.

The issue comes when on the actual product page. In the Media drop down menu only 3 of the 4 available options show.

Im really confused why, as I can’t see any reason for this.

Any help would be greatly appreciated.

Here is a link to the test page I’m trying to sort.
