Product Categories - WooCommerce

Hope you are well,

I have recently uploaded woo commerce and still figuring things out.

But have set up categories and have a large amount of products. Just setting up the menu structure and shopping. But the links to the products are not working. I think I may have set something wrong.

When I chose categories and move over, then I see it changes to column. See attached.

My site is under maintenance so let me know if you need access.
