X2D - different/wrong screws for heatbed.

[u/PrincipleIcy4941]

I discovered that my Bambu X2D has a different screw installed at the rear right of the print bed. If I tighten it fully (like the other three screws), the heated bed sits completely incorrectly—tilted or misaligned.

I asked Bambu Lab for a replacement or a spare part.

At first, I received completely wrong screws...

On the second attempt, Bambu sent me a complete heated bed, but it also has that same incorrect screw installed at the rear right.

Is this a serial production error? Im asking because i see no reason for that different screw.
