Listing Loop Linked to Facebook & Twitter Links

Ok, so it’s nothing to do with how I’ve it set up or the fact that the links are facebook or twitter.. But it’s because the links for faebook and twitter are different to the website link.

If I insert my website link in the web link, facebook and twitter link fields it will accept it.
But if I change the facebook and twitter link fields to a different address than the web link field address then it won’t accept it.
I have tried inputting my website, facebook, twitter, and other external website urls in the facebook and twitter fields.
So there is something in the code saying that can’t have more than one website link, and if they don’t match causes it to loop.

Please has anyone suggesstions / solution because I need to be able to allow customers to input their social media pages links in their ads.

Thanks
