1 Gig $50/month 5 years guarantee is shown as $60/month?

Hi all, I just got the 1Gig $50/month plan right from the link that Comcast advertised when accessing xfinity.com. Now that I am online after activating the new modem and login to xfinity account, I see my internet plan is shown as $60/month 1Gig for 5 years.

Why is it shown as $60/month and not $50/month? It is also saying I am eligible for the $10 discount if doing autopay and paper billing. For those of you who has this plan what it is showing in your case?

Another confusion is if I click on “change plan” I can see the 1Gig $50/month for 5 years as an option I can select to change to. This is so kind of weird and confusing.
