Amazon t-shirt listings new Collar Style attribute help

Hi,

I have been trying to list a few t-shirts on Amazon but when I do there is a mandatory field “Collar Style” for a t-shirt I would expect to see crew neck but all the options appear to be for shirts. Has anyone seen this and know what to do?

Maybe I am being a bit thick but for the life of me i can’t figure it out. I have contacted support but noting on it for over a week – so thought I would ask here.

Thanks.
