upgrade finder is reccomending wind relics, the mm hunter artifact has a storm relic slot, not a wind relic slot, this is also wrong on wowhead, which is possibly the reason it is wrong here, I have also posted on wowhead about the error.
Wind and Storm are the same thing - it’s something with the item data we get from the game.
Yeah it was Wind back in Legion alpha and beta, but they renamed it to Storm. We can try to update the display name… it’s on the todo list.
