[MC-242112] Ghost block left behind when a gravity block falls

When a gravity block falls, the block is still there, and it duplicates itself. A ghost block is left behind at the original position(before fall), and if you update the block it will re-appear, duplicating the block. It broke my redstone machine. Detailed description is in attached video.

Does this happen to you in a completely new world? Are there any data packs active? Or is it possible that there's some command block running that messes with falling blocks?

If the answer is no to all of these questions, could you please give us a download of your world? Thank you!

Cannot reproduce; even with the provided world.

This also happens in pre-6. The ghost block has no hitbox now, but still continues to duplicate. Tested with concrete powder(light blue) this time.

OOOOHHH I found the problem. A command block is repeatedly setting the "Time" nbt of falling blocks to 1. I think that's the problem.
