Bokeh DOF on CineCameraActor?

When checking “BokehDOF”, the Depth of Field is gone - it just doesn’t show any effect.
When switching to “Circle” or “Gaussian” the depth of field works.

However, I prefer to use “BokehDOF”!

What else do I have to activate, that the “BokehDOF” will be activated and will be visible in the viewport and through my camera?

Thanks a lot!

Anyone knows? Tested it today again… but no luck… is it a bug?
