I have a rather strange problem that Google wasn't any help in solving. I recently got a Thrustmaster T300 GT with TH8A shifter. Everything works fine in PC2 except when I run a career race. I'll go through practice and qualifying with no issues, but for the first 5 seconds or so of a race I can't shift with the paddles on the steering wheel. Thankfully I can use the TH8A for the first few seconds so that I'm not in a terrible position place wise and then switch to the paddles, but I can't figure out what's going on or how to fix it.

Here's what I've tried so far:
-Disconnecting TH8A
-Running race with warm up lap set to manual on and off

Other than that I'm not really sure what to do. Since the paddle shifters work in all other aspects of the game I'm thinking this has to be a software bug, but it would be odd that others aren't experiencing it. Would be interested to hear any suggestions. Oh, and yes, I have the paddles mapped in the settings.
