Why won't eBay allow me to print Standard Envelope labels for my Dessert Storm Trading Cards?

[billscollectibletreasures]

I have listed a bunch of Pro Set Dessert Storm Trading cards. During the listing process it allowed me to list with Standard Envelope Shipping. However, when an item sold and I went to print a label the Standard Envelope option was not available even when the buyer chooses it! What did I do wrong? Collectibles > Militaria > Desert Storm (1990-91) > Original Period Items is the catagory I'm using. Is that causing the problem? It's a Trading Card!! Please help if you know how to fix this!

Thanks,

Bill

Yes, the category is the problem.  It needed to be in a trading card category.
