Need help selling shoes. Amazon existing listing has wrong important info

So I have sold on Amazon before and left for while. Now I remember why. lol.

So in a nutshell I have a bunch on puma shoes in different colors and many sizes of each.

The shoes I have are all in women’s size and even the label and tags on the shoes shows them as Womens. For example women SZ 7.5 US W.

When I scanned like 20 different ones, they are all already on Amazon as the upc has already been added by someone else before.

The thing is they all are showing in the tittle as men size. For example.

“PUMA Womens Stewie 1 Causing Trouble Basketball Sneakers Athletic Shoes – Pink – Size 9.5 M”

See how it says 9.5 M? It’s not. It’s 9.5 W. I would even like to add US next to it.

It’s literally like this for over 40 different skus I have.

I know this will cause returns and poor buyers experience if I use the listing they have.

Seller support is useless as I expected in helping.

Anyone have suggestions on how to to move forward?
