I apologize as I don't know for sure if this is an Upright issue - or maybe it's an eBay one?

We are listing some small lots of men's & women's clothing and are putting it into the eBay clothing > wholesale (small or large lots) > then Men's or Women's categories as shown in the screen capture top section. We are trying to list the majority of the clothes in groups by size, In the Optional Specifics area we could put the size but for some reason in both Men's and Women's categories the only options for sizing are all baby/toddler sizes? If I search for XXL, etc. they do not appear as options in the drop down at all. I was curious if this is some sort of category mapping issue?

Since the size is optional for the wholesale section we can leave it off, but thought I would point it out.

Thank you!
