Can't modify space transform in Control rig

Hi, now i have some problem when using space in control rig.

Can’t modify space transform in detail pannel. enter a value and press enter, then value didn’t change. keep original value.

Right now, I am working on a method of creating a control, moving it to the desired location, creating a space as a child, and then converting the space to a parent, but it is too cumbersome.

is there any other way to change space transform?
