When viewing the classified, the filter for Sold status does not give me a choice. I can only view "Unsold Items Only"
My profile say to show all. How can I see all ads?

this means you are viewing in the "All Ads" tab. Click any of the other tabs at the top of the listings (i.e. classifieds, auction, wanted, trade) and the sold/unsold option reappears.

with the mix of auction/classified under all ads the "unsold" switch takes less meaning because of the auction mix
