Unable to calibrate G27 wheel

"Control scheme" is "wheel", Make "Logitech", Model "G27"
In "Edit Assignments" the "Steer left and right" are assigned to the G27 axis.
However if I try to calibrate the wheel the red horizontal bar does not move and in game there is no steering.
All 3 pedals calibrate correctly and work correctly in game.
Can anyone offer any helpful advice please?

The wheel and pedals work perfectly in rFactor2
