Randomly spawning end platforms

Working on removing the entire end island. Noticed that if i log out and back in while in the end dimension, these platforms will generate at random even after i've mined them away. Seems to do this within the area of the end gateways in areas were the end island used to be there anything i can do to prevent this?
Also happens when leaving, coming back to the end, or just unloading then reloading the chunks
