I'm seeing 34 active listings. Usually if something isn't working, cleaning out cookies and cache often fixes eBay issues. Make sure when you clear out, you change it to "all time", otherwise it only cleans out the last month's worth.

Edited to add: When you go in to clear everything, be sure to untick the other options that will be ticked by default, otherwise you will lose saved passwords and other stuff you probably don't want to lose. Clearing cache will also log you out of everything, so you'll need to log back in to any sites you like to leave logged in.
