It looks like someone replaced the center plastic piece with the t hook on it with the 3 inch version. You should have a 6 inch which will keep the door much closer to a 90 degree angle to the camper and allow you to have the door open with the awning out.
I would suggest keeping some extra on hand since it's only a matter of time before you forget its hooked up and go to shut the door and break it. This is probably why yours has the wrong one on it.
Here is a link to one of many options.
