I finally found the exact issue. When you fully pull the door handle it slides out of the carrier, blocking the carrier from going back into standard position. The door handle can't move either because the carrier blocks it. You have to push/pull the carrier around a bit for it to shoot back into its original place, but the carrier doesn't take the handle with him.
I tried it with the handle from the rear door on the new carrier and it still has this issue. Even though none of the other doors have this issue. I'm so confused why 2 seemingly perfect parts can have an issue like this.
I added a video of me explaining the issue to my friend, so don't mind the Dutch speaking, haha.
I would be very surprised if you could give me a solution, but who knows. Probably forced to go to a garage anyway.
