This is Jonathan from Kontera. Looking over your Hubs, you implemented your Kontera tag correctly and Kontera ads are displaying over your content.
With HubPages, Kontera implementation has been simplified, so you don't need to worry about Kontera's HTML tag, you just need to implement, what in your case was the 6-digit code 154644, which is your Kontera Publisher number, on your HubPages Affiliate Settings page.
