Pages are all the same after the latest update

Earlier I looked at my sight and it was the way I left it, the home page had a slider and its own content and the about us pages had its own content. In the dashboard I noticed there was an update for Upfront so I updated. Now all of my pages have the same content which is from the about us page. If I change anything on any page it changes all of them. Does this have to do with the template settings? From what I can tell I have to use a different template for each page which is a problem because the Fixer theme is only showing three templates which would mean I can only create a three page website. Is this correct or am I missing something here?
