The "V" jam cleat on the batten end also ONLY cleats in one direction. You may have the lines run wrong. That is a very common mistake.
Try these files. The first is from our manuals on how to do it (pdf). It also shows how to tuck the end of the line under so it will not shake out of the v cleat. The second is just an image file that shows the proper threading.
