The add to cart button appears twice

Hello,

After configuring the plugin so that only certain categories of products can be purchased, the add to cart button appears twice on the store pages.

Here is an illustrated example : https://image.noelshack.com/fichiers/2018/40/1/1538377025-exemple-catalogue.png

And here the plugin configuration : https://image.noelshack.com/fichiers/2018/40/1/1538377190-exemple-configuration.png

Thanks in advance,
