Hi harrisonwindsor,
I'm uncertain which specific category numbers you may be referring to, but I just reviewed a couple categories you have used within the "Jewelry & Watches > Fine Jewelry" section, including category #'s 164343, 164333, and 164319, and found that the attributes displayed by default in the Custom Item Specifics area on our site match those displayed on eBay's Sell your Item form.
If you were seeing different default attributes in the Custom Item Specifics section for those categories previously, it appears that eBay must have made a chance to the default Item Specifics attributes that are provided for those categories.
If you notice any categories for which the default attributes that appear in the Custom Item Specifics section on our site differ from the default Item Specifics attributes provided on the eBay Sell your Item form, please let out customer support team know and we will look into it further.
You can contact our customer support team at any time by mousing over the “Help” tab within your account and selecting the “File Support Case” option.
