Fit Quiz typically syncs with your product catalog at the time of the initial integration. It means, that if you've since added new products, they may not be yet reflected in the "Product Mapping" table.

To fix this, you will need to resync your catalog by clicking the "Resync catalog" button right-hand corner of the "Product Mapping" screen.
