G27 Seperate Throttle and Brake Axis Not Working

Hi,
I have a logitech g27 and when you go into the setting where the force feed back adjuster and all that is, the box where it says combined axis i have to un-tick for the game for independent axis. But when i test the gas and brake, they only increase and decrease in increments of 50%. Then when you go into beamng, it messes with the clutch like the gas, brake and clutch are all on the same axis then. I use to love this game when it worked correctly with my wheel. I contacted the Logitech guys but no one on the phone knows what their talking about and just send a report in. They have replaced it for me but it must be on the software end. I have been trying to figure this out for months maybe a year now. I have looked on line and it looks like no one has had this problem. Please help, thank you so much!
