Honeycomb Bravo Axis setup

I am having an issue with the Bravo setup,
I am on PC using MS Store version and launching from Xbox App.`
Dev mode is off.
I have assigned throttle 1&2 to Throttle Axis and have Sensitivity at default, but the movement of the Bravo controls show that as you physically move the control up to full throttle, the Menu Axis jumps immediately to 50%, then travels in linear fashion.
How do I prevent this jump to 50% from happening?
I deleted my Profiles and re mapped the quadrant and still the same.
I now notice as well the Mixture levers don’t move in the Sim, even though they are mapped.
Using version.
Any help accepted. I have emailed Honeycomb Zendesk to ask last week but no reply so far.
