Sticky pistons cause block disappearance

A bug I have involves a redstone circuit where a button removes some floor blocks and raises a series of stairs (a classic secret passage where the staircase opens, allowing me to go down, and I close it from the inside using another button). The problem is that the blocks next to the sticky pistons completely disappear from the world, forcing me to replace them with new ones every time. This mechanism is located just a few chunks away from the spawn point in my world. The seed is 1558540552.

I am playing on a PlayStation 4 Pro with the latest console software version, 10.50.
