Multiple Storefronts All Sharing Product Reviews?

I have a client running three storefronts off one CSC 4.2.4 install. She just noticed that product reviews are being shared on all three storefronts. I can't seem to find any way to not share the reviews, does anyone know how to do this?

Please check addon settings

And be sure you set them in the context of the storefront versus all stores.

Thanks all, it was that option on the addon settings. Not a very good description of what that checkbox is for.

And be sure you set them in the context of the storefront versus all stores.

FYI In 4.2.4 that option does not show up unless you are on "All Stores".
