Brush entity vanishes

[Wichilie2]

Hey, I'm trying to create a brush entity by pressing Ctrl+T with a brush selected. This works as expected:

However, once I deselect the brush and reselect it it's like the brush forgot that it's a brush entity and all the options are gone:

Does anyone know what's going on here?

Kinda interesting that having it set to solid opens a panel called "Object_Properties" right haha
