TCA Issue

Hi, I have an issue with my Thrustmaster TCA throttle, for example, take the default C208, if my hardware throttles are at the idle detent, the C208 isn’t, only when my TCA is in max rev, does the C208 become idle. Thinking about it MSFS must think the entire axis is throttle and that it doesn’t have reverse thrust section, is there anyway to fix this? Thanks
