The broken redstone systems in ancient cities (Minecraft Preview).

In Windows 10's Minecraft Preview, from time to time in old cities the redstone system that opens the door is very buggy. Honestly, I don't know if this is a bug, but it's bizarre the way it appears. I just want to let you know that in the video I left below, I didn't destroy any blocks. I am teleported to an ancient city and found the redstone system that opens the door this way. Please if this is a bug, please fix it.
