Sculk sensors generated in superflat world are not correctly initialized

The bug

MC-207251 is partially fixed. However only the sculk sensor where you spawn on it will react to the sounds, the others will not work but you have to walk on the others sculk sensors for them to work properly.

I attached a video demonstrating this issue.

How to reproduce

• Create a flat world using this preset :

minecraft:bedrock,2*minecraft:dirt,minecraft:sculk_sensor;minecraft:plains 

• Fly above the ground and land
• Note that only the sculk sensor where you spawn on it will react to land sound
