First picture, you're standing in a parcel with a DIFFERENT NAME and PLOT SIZE than the one listed - with a property line showing right next to you.
Third picture, check the presence of ban-lines and the difference in plot sizes and Names - methinks you are actually not on the parcel that is listed for sale, you're next-door to it.
The second picture, however, is a different story. Same name, same size. My guess is that it was bought, or changed hands avatar-to-group or some such, and that resulted in a listing that wasn't purged from the DB fast enough. However, this is the only one of your three examples that really shows unexpected data.
