eBay expect their sellers to be responsible and to list items correctly and place in the correct category true, but with over 7 bilion listings on at any one time, they cannot possibly check each and every one for errors.
You could send the seller a polite message, they may not realise what they have done.
I have in the past, made a few innocent mistakes and received a polite message pointing these out for which I was grateful and immediately corrected the listing.
It's for the seller's advantage to list correctly, less likelihood of cases for item not as desctibed to be opened.
