I can check it out, but it is very likely that I can only apply the variation description and the SKU in this case and only for the index table engine. Regular engine will not work with this as the variation are separate post type objects, not stored as part of the product.
Can you please also add temporary (s)FTP access? I will have to make change to the files and any mistake in the code could lead to a site error which I can’t revert from the back-end.
