We’re having the same issue with the double listing, but it’s not Yoast related. You can see it here at our sandbox website: https://www.webfromthewild.com/rey-2013/listings/ Clicking into any one of the listings shows the listing information twice on the page, by default.
We’re using WordPress 3.6, and the latest FireStorm Plugin )Version 2.07.03) installed. If this can get resolved, we ‘ll be upgrading to the PRO features immediately ?? Until then, we’re just scratching our heads…
Thanks in advance for any help!
