why dosent work hlod window?

window hlod all time hiden, hlod volume spawned and window still hiden, i have a main hlod and add a new volume, this is right way or i do something wrong?

and i find a bug in a editor, then start build hlod without volume hlod this is stuck on a infinite build, may be need add a window with message “no one volumetric hlod instances doesn’t find for a build, you should be add it for a start build hlod map”

i mean this window
