Unit Height

[Mind]

I adjusted a custom units height to -45. Apparently, negative values are allowed for this specific option by default, but the "Allow negative real values in Object Editor" option is checked.
Yet, the custom unit in questions height remains default… Why?

Movement type must be fly.

Movement Minimum height is when he flies over objects & terrain.
Movement height is the default.

Both values must be set, minimum must be less than the default.
