Furnaces cannot be removed.

I tried to remove these furnaces from my world and they bugged out and cannot be removed by anything, including explosions, i haven't yet found any way of removing them as they seem invincible, the furnaces can be pushed to the side but all of them go back to their original positions once the piston retracts, and can't be pushed downwards.

 

I only have resource packs added on the world and they were update last week,

 

This should be the world, Survival (Vanilla).mcworld

the coordinates for the furnaces are: 2138 59 622
