Eraser Bug in Storyboard Pro 6 - SBP6 - Doesn't show active eraser brush size during erasing

In the new Storyboard Pro 6, when I use the eraser, and hold down the button or push on the pen, I don’t see a display of the eraser size, and it doesn’t show the lines being erased as I’m erasing it. Once I let up on the mouse button, or pen, whatever I erased does disappear.
However, I can’t see what I’m erasing as I’m doing it. So, I have to guess if I got it right.
Anyone else have this problem? Or is there a setting in the preferences I don’t know about?

Thanks.
