Post being duplicated, other posts not appearing.

client has a custom post type, called Rugs – with a custom taxonomy of Rug Type. To this point all has been working fine, however recently I can confirm that client has attempted to publish three new rugs to a “New Arrivals” rug type, Rug A, Rug B and Rug C.

Rug A and Rug B, though published are not appearing at all in the S&F listing. I can view those rugs individual and can confirm that they exist and that they are in the correct Taxonomy term.

Rug C – however appears twice in that listing, and not side by side one on page 1 and one on page 2. I’ve confirmed that it is the same rug, as if i change the name or slug, it changes it for both rug posts.

I’m very surprised by this behavior and can’t seem to figure out where the issue stems from.
