If it says, "active", that is fine. I check one of your hubs HTML code. If your Google adsense ID is ca-pub-33XXXXX5232, it is working correctly.
Anyway, you can create a "URL channel" to see HubPages earnings and page impressions.
Log into Google adsense, Adsense setup --> Channels --> URL Channels --> + Add new URL channels
Insert "http://hubpages.com" as the URL. Then you can see earning, impressions and clicks from HubPages.
