"Reverting movement" issues

I can't open issues on github because I am limited.

But the issue I am getting is that I'm is still getting "reverting movements" in console even though I have my

Code:

anti-cheat:
  #If false, will try to prevent speed and noclip cheats. May cause movement issues with some blocks which are not yet properly implemented.
  allow-movement-cheats: true
  #If false, times block breaks to ensure players are not cheating. May cause issues with some blocks which are not yet properly implemented.
  allow-instabreak: true

allow movement cheats set to true

 

This sometimes happens when a player flies too fast in creative mode

 

sometimes when the player jumps it falls down quickly.
as if he were attracted to the ground.

same thing if the player is on a staircase except he is kick for FLY

 

Yes that cause many lag but i have good stuff

 

No, he means that it's possibly caused by lag (which it sometimes is). What "stuff" do you mean?
