This bug is still not fixed as it is still working, I am not fully sure if this is considered a bug but it makes no sense to me. I am a professional redstone and command block engineer and I do not understand anything on how these BUD switches work. It makes no logical sense. Also pistons need to be sped up in bedrock because I think the bug may have something to do with that.

Below is the design for a BUD switch in minecraft bedrock.
