Am placed pit where is fake wall and it turns into real wall
When am remove that pit fake wall still is real wall
Pit turns fake wall into real forever, until delete and place it again

(its not temporary glitch am test it few times)

The issue is that ESB independently tracks whether a square is "open" or "wall," regardless of the presence of a fake wall. If the square is set to be a wall, it will be treated as an obstacle even if a fake wall is present.

(There are probably better ways to solve this, but, for now, you can be aware of this, and make sure fake walls are always placed on open squares)
