Facebook on Tablet is redirected incorrectly

So I have the plugin set to not redirect tablets to he mobile site and if I open a browser on my ipad mini and enter the URL http://grayvermont.com it takes me to the regular site.

However, if I click on a link from either the Facebook App or Facebook from the browser on my tablet it takes me to the mobile site.

Here is a link from Facebook as an example: http://grayvermont.com/homes-for-sale-details/53-SIMPSON-COURT-SOUTH-BURLINGTON-VT-05403/4380615/23/

The facebook page is: https://www.facebook.com/GrayGroupRealEstate
