Bare products are essential to the app functioning properly.  Without these products enabled on your store your customers will not be able to successfully checkout.
Don't edit product type or the URL handle as these values are critical for the app to function.  Other data, like description, cost, tags, etc are editable.  To edit product pricing, we recommend making those changes in the Customized dashboard (Products menu option) to keep the app in sync with your Shopify store.
You can easily exclude these products from showing in collections by adding a filter to your collection.  To do this, filter out product type that equal Bare Product.
