Small end portals just teleport plater back to center of ender dragon arena

After restarting the game, player is unable to use the small end portals that spawn after defeating the Ender Dragon. It teleports player a few blocks away from the large portal in the center of the arena- to start the credits. (I'm very aware i can just cheat the game and make a new one but i'm trying to keep the world "Legit" and would rather not bridge across a thousand blocks.
