conflict with Woocommerce options

I wanted to use this to utilize radio buttons on a product where the options do not affect the price. Works great. BUT when I use the Woocommerce attributes for a different product, this plugin appears to be intefering. I cannot add to cart and instead get a “please-choose-product-option9s)” error. If I disable this plugin I don’t get that problem. Is there a setting I’m missing?
