I have e-comerce plugin on my site and all users who has role of Author could also publish products on the site as well as posts. I didn't want that so I have created a new Role (by User Role Editor) called Seller (copied all capabilities from Author role) and I have used your plugin to assign post type "Product" only for the Seller role (I just check-boxed Seller on More Types so users can publish, edit and delete products).
As a result the capability of posting Products has disapeared from Author's role, which is good! But it didn't appear in the Seller role. I still can see it from Admin User though. But I need it for Seller role too. Did I do something wrong?
