I guess I'm not completely understanding what's happening. The slide topper awning is attached to the side of the coach, and attached to the awning tube, and the window awning is a piece of the slide topper awning. The awning strap is slid into the awning tube in a slot. As I understand it, when the slide opens, it unrolls the topper awning which tightens the spring in the awning tube. when you pull on the awning strap. it also tightens the awning tube spring and unrolls the window awning. Using the awning rod, you release the pressure on the awning strap, the awning tube springs will start to rotate the tube which will wind up the window awning onto the awning tube.
The only thing I can think of that would make the window awning go in pleats is if the awning tube is not rotating. When you remove the awning strap, do you use the metal awning rod to let the spring tension roll up the awning? If not that mey be what's causing the problem. That's my best guess.
