Noticed ASIN is in wrong category

I was looking at my fba charges yesterday and I noticed most but not all variations were being charged the wrong category. I submitted a ticket and they told me I need to delete the listing and add product again. What’s confusing to me is when I go to the product page on Amazon, it’s in the right category. Amazon is just charging me a higher percentage and adding an apparel fee for something thats not apparel. Any recommendations on how to fix this? I’m kind of nervous about deleting the listing and why would 1 variation be fine and all the others be charged a different category?
