Need Help With Uploading Products

Hi there,

I have uploaded products to a clients page (can’t share the link due to privacy) but I’m facing an issue, that is the products aren’t showing under the designated category. For example: home page, Tabs assigned for different pages, Sunglass tab lists different sunglass products, but a new brand that I have uploaded isn’t showing in the drop-down here. Do I need to setup a page so that it will be visible?
Thanks in advance.
