Logitech Trackball M570- stopped Zooming

Moved from a decent Windows PC to a new/better one. Installed the Logitech driver for the mouse and keyboard as usual (moved the one I was using over to the new). Works fine except on FlightAware I’ve lost the ability to use the center wheel to zoom in/out on the live tracking map pages. It works fine doing so on Google Maps, but it ignores both wheel directions on the background map in FA. I reverted to using the +/- tool in the top left.

Using the Logitech tool and reassigning the wheel from Default to Zoom it then zooms the entire webpage, not just the map (yes, even after clicking on the map to focus that image).

Any ideas how to get it back? Thanks in advance.
