I had this installed less than one week ago and noticed after installation the separation where the black and stainless steel in the back are. Is this supposed to look like this? I see the metal piece in the stock pictures, but this looks way too separated to me and I'm not sure the purpose? No one seems to be able to tell me if it's supposed to look like this or it's a defect. Won't be able to swap out a new one until availability in October. Can someone help?
