Problem with bsp geometry

Hello i have some problem with BSP. Im new so looks like i push some wrong button. And now i cant select “polygons” or faces of my geometry. Can select only points. Eearlier i can do it and just select and drag face. (extrude and others options in edit mode gray not active)
What already done.
I make another BSP brush, chek if editor mode on (last bookmark), and restore default editor settings this not help.
