Static rope hang FOF ERROR

[MrBoingBD]

I'm having some issue in my Level mod, With Rope hang segments:

"ERROR: A FOF tagged 40 has a top height below its bottom."
"ERROR: A FOF tagged 35 has a top height below its bottom."
"ERROR: A FOF tagged 27 has a top height below its bottom."

And Hanging on a rope will for some reason work if I touch it from above, but from a certain angle.
It teleports me into the void outside the level itself.

You’ve mixed up the floor and ceiling heights of your FOF.
