Sorry if I did not answer that part. But now I am confused. I looked again and I see you placed your Amazon capsule at the bottom, under the "comments" capsule. That is how I missed it. But I'm confused because you say that it is not active. What do you mean? It is appearing, so I assume that means it is active. But I do suggest you move it up where people will see it.
As for the ratings, your profile has a rating and your individual hub get rated too. I stumbled upon other good hubs that explained how it all gets calculated, and other Hubbers have written very good and detailed answers to that question. You can find these hubs by using the search box at the top of any page. Search for "hub scores" under "hubs" and you'll find a lot of useful info.
