Ionic back button not working even though ionicHistory back view exists

My ionic back button doesn’t do anything when it is being clicked even though, when I print out the version history, it shows that there is a back view. Also for some reason $ionicHistory.enabledBack() is returning false, even though the back view exists and the back view and current view have the same id. @mhartington can you help?

Here’s a snapshot of the console.

I know I tagged you in the post, but I was hoping @mhartington, you could take a quick look at this?
