Selling/Buying Rings in CS aka Auction House

Currently if you access the CS you will only see options to buy helms/weapons/armor/shields/crafting you do not get the option to purchase rings. To purchase rings you need to click on the CS, and then hit the sell button. While on the sell screen you have to click on the rings option. Once the rings option is selected on the sell screen you have to click on the button that takes you back to the buy screen.

Crazy right? I didn't even know you could buy rings out of the CS until a month or two ago and I've been playing this game since 2010! Is there anyway you guys can fix this? Thanks in advance.
