Pay-to-join plugin issue

So I want to add different attributes to my products, but because I am choosing the product data as “Pay to join” it limits me to user the different option woocommerce provides.

I want to be able to add attributes to the products, but as you can clearly see, I am not able to do this when selecting “pay to join”. I NEED a way to fix this, especially since we have to pay for the plugin which clearly limits to your use of WooCommerce.

Please, give me a way to add attributes.
