Interesting.... There are a pair of pins inside those springs that are supposed to be pressed into the black plate that came off. Those pins are not supposed to come out of that plate, they align the plate in the springs and prevent it from coming out. But I can plainly see in your photo that neither pin is in the plate where they should be.
I don't think "I" would send it back, I personally would mix up a small batch of 2 part epoxy and would epoxy the pins in their holes and make sure they never came out again. If you need help I can help with photos to show you how mine looks.
I guess the quality on these is all over the place, mine so far seems to be put together right.
