Tv fireplace stand

New fireplace tv stand from Wayfair. Just put together yesterday. It has changing color lights and adjustable heat. The shelves sides also have led lights on the top. There is a small gap between the fireplace and the back of tv stand where you can see the cords a little and behind it. Idk why. We put it together right so I guess it’s just a quality error. Comes with remote. Selling cheap.
