How Can I create an IMM Curve Brush with Plane?

Hello
I just need Single flat Mesh Curve Brush.
It was possible before version 2021.6.
Ever since the ExtrudeProfile function was created, My Plane Curve Brush automatically changes to Extruded results.
Q
I just make Single mesh object like that jpg.
How can I turn off the ExtrudeProfile function?
It would be very disappointing if the function could not be turned off.
