TwoTrees TTS-55 Pro Confusing Parts in box

Mine came with two setup blocks, one silver and one black.
My Laser itself, the Laser itself, has a Red metal block mounted under the bottom of the laser.
Somehow, I think I got a mixed bag of goodies in my box.

Mine came with the same parts - I took the red metal block off (as I don’t have air assist) and used the magnetic red cover on it instead until I get air assist.
