What version(s) of WoW are you using?

Classic

What version of Auctionator?

11.0.11

What isn't working? What was supposed to happen?

"Armor" section is missing on the "Selling" tab - and the items are not appearing anywhere on the selling tab, although they are in my bag.
I have several BoE items to list, yet they do not appear, nor does the "Armor" section of the selling tab appear.
I sent the items to another character and the same issue occurred.

Are you experiencing any lua errors

I'm not getting any error notices.

Anything else?

No response

Its not missing for me in classic era. Do you have the items hidden? Right-click any item in the list and click the "Unhide all" option.
