Product showing in collection (active) but not on website

I have a product (see below) which I have added to my “Polo” and “Hi Vis” collection in Shopify. It only shows up in my “Hi Vis” collection on my website, not my “Polo” collection? Inventory is not tracked so it can still stay up unless I manually make it inactive so not sure how to fix this?

thank you so much, i had to add the tag “shirt” :slight_smile:
