I have a listing for T-shirts in 2 colors (black, green) and 4 sizes (M, L, XL, 2XL), total should be 8 combinations but I noticed I was missing 1 (Green, 2XL).
I click on ADD COMBINATION and I get the fields to fill in for Size, Color, Qty and Price.
However the other variations also have Size Type but when I try to create a new variation I don't have that option.
See screenshot below, the blue highlighted row is for my "new" variation, see how in the column for Size Type I can only Enter Size, then on column for Size I can enter the Color, on Column for Color I can only enter Qty and on the Column for Qty I can only enter the price. Basically I field is missing and everything is shifted so it does not line up.

So I then decided to remove the "Size Type" option from the variations page which is fine, but then on the main listing It asks me to enter the "Size Type" AND "Size" for the whole listing, which doesn't make sense since I have 8 combinations, please see:

I entered a value anyways but when I try to "Update Listing" it just says "We are having trouble updating your listing right now, try later"
Why do I always have problems when editing a current listing with variations with eBay?
I would start all over except that I have so many sales on this listing and I don't want to lose that counter, any tips?
