Set Visibility to the products attributes for simple products

Dear sir / madam,

We have been using your plugin with great pleasure to add our Pre made Attributes (before using BEAR) to all of our products.

Recently we noticed that the Attributes are all visible on the product page (In the tab: Additional information). The thing is: We do not want any of these attributes to be visibile on the product page (not for our simple products and not for our variable products).

Now we did find out how to change the visibility of attributes on product page for variable products (in the advanced tab). But how do we uncheck it in bulk for our simple products?

Looking forward to hear from you.

Kind regards.

Martijn
