product attribute tab

I use this plug in with woocommerce 3.0.7.
After I’ve imported all products to woocommerce, I’ve activated this plug in.
But if I clik the tab ‘woof’ in woocommerce instelling tab in admin, something goes wrong.

Because I see wrong ‘img tag’ or ‘div with some class’ replaces with other div if I open the page of the product tab with product attribute on the website.
I didn’t even set the structure of woof. I didn’t do anything further with woof. Just opened the tab in admin.

What is the problem? Can somebody help me?
