Sorry, I've been away for so long. I didn't realize the teleport pad wasn't working. I've updated it to v1.1.1 (for mc1.12.2) which uses the latest GottschCore and Forge. You need to place 2 teleport pads, one above the other (however far apart), but the same x,z coordinate. Then open the teleport's inventory and load glowstone - that is it's fuel. You should then be able to teleport.
