From time to time the system does not allow us to view a member's listings, this is happening now to me, and I cannot see your items for sale, so cannot give you the definitive answer you need.
However, it's a fairly new change that buyers, cannot view / see the Buy it Now on their own listings, but be assured, everyone else can and c an buy your items via the BIN button.
Or , if you have an auction item and it has a bid, then the Buy it Now option disappears, and the sale runs along in auction style only, in fairness to the other bidder(s).
