Nice Installation, Lacks Completeness

I installed this plugin and it pulled my paid store products and made pins for them, just as I wanted. It took a few days for it to be activated and completed, but it worked wonderfully. Then I received 2 warnings, per product, for every product, from Pinterest – due to condition not being stated and Google taxonomy not being stated. I went back in and added that information to my products and updated the products, but the information is not being retained. After the update, the fields resort back to default and blank and my time has been wasted. Please complete your plug-in with fidelity, so I can come back and change my rating. Thanks!
