Listings duplicating themselves

Hi,

I have been adding listings to populate my site. I do this in the front end by using the social importer add on and then going to the back end to publish the listing. Most of my listings have been ok but there have been a few which, when I do to the CPT and view the listings, I can see the listing has duplicated itself many times. If I don’t permanently delete them all, new versions of the same listing will keep appearing.

I also notice the ‘bug’ listings have words in their descriptions which my payment packages don’t allow for at the moment. They are not words I’ve typed and must’ve come from facebook.

Attached is a screen shot of an example listing which occurred this evening. I have now had to permanently delete them all.

Do you know why this may be happening or how I can stop it please?

Thank you very much for your help.

Thanks
Paula
