I was trying to build a piston elevator in Minecraft bedrock but the elevator kept going up and down when I was trying to only send it up. When I tried to send it up, it went up a bit but went back down. I noticed that the pistons kept teleporting 1 block up and down over and over again. It duplicated itself for 0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001 seconds and the clone elevator disappeared. It was also making a weird piston noise that it wasn’t supposed to make. When it was sent up, it went up, but then it went down and hit the ground. Then the elevator clinged to dirt blocks and carried them. The dirt block issue isn't the issue. It's supposed to behave like that.
