Hey all
So i just had some help from a wonder Shopify Rep - Ryan - Amazing!!! Anyhow he totally fixed this issue for me.
In the Navigation settings/menu area where you have your menu tabs (Accessories, Decor, jewellery, Toys etc)… he removed all tags from each of the menu options and that 100% solved all the problems. Now when i view my store and click on one of the catalogues…it shows all the products that belong in that catalogue.
I hope that this helps someone else…all else fails, chat with Shopify Peeps…they’re fantastic!!!
