SmushPro gives incorrect image statistics - does not Smush

I have a problem smushing images - smushing rating is 25% right now (on HummingBird). When I try to configure smushit, I get the following

1811 / 1570 images smushed and WP Smush Pro is actually set up - running a bulk smush doesn't do anything ... wondering whether this can be fixed?

I have also granted access to the installation right now.

Cheers
David
