Polybrush randomization settings vanished

I’ve tested Polybrush a bit for prefab scattering and it seemed like it would do the trick - I loaded my brush with prefabs and set a random scale/rotation variable and (while crazy laggy) it worked. However once I selected my mesh in the game map scene and tried to use it again, all the controls below the Current Palette section in the palette were gone - no way to randomize scale/rotation. Does anyone know how to get it back?!

never mind - Apparently these controls only appear when you’ve selected one of the prefabs in your palette.

no they do not ? those settings are gone or what i am doing wrong

they tricked me too lol. bad UI design. it is better to grey out UI elements than to make them disappear entirely
