First End Portal Teleporting me to Main Portal

The very first End Portal after defeating the Ender Dragon isn't functioning properly. At first the End portal in the Air would teleport me to an Area where the Nearest End City would be. But now when I attempt to go through the End portal, it would just teleport me right to the End Game Portal. This didn't start happening until after I curiously hit the End portal with the Pickaxe wondering if it would break and could aquire. Maybe I did break it?
