why do product/inventory search in the dashboard give different results for the same search term?

I’m struggling to understand why in the shopify dashboard if I go to products and search for everfest extended I get this truncated result which starts at R and goes to the end of the everfest collection returning items with variant “extended”

But when I use the exact same search term in inventory, it gives the correct result start from a collection item beginning with A:

There is absolutely NO difference in the way the items in the collection are named or categorized.

This is a huge pain to work with so an explanation would be so helpful.

Thanks!
