The hubs that are not featured will not show up on your main page unless you go into your profile and adjust some things. Go into 'Edit your profile', then go down to the bottom of the page where it asks if you want all of your hubs to show. Check the correct one that will show all of your hubs. Then they will all show.
Google will not see your hubs that are not featured. Edit them and in about 24 hours, they will be featured again. Then Google will start seeing them. That may help the problem and it may not. Google Adsense has some strange things that they do not like.
