Wreckfest - Telemetry gets corrupted after finishing one race

[InsertUserHere]

In single player custom events, after a race is finished, the credits earned screen plays out and the player is sent back to choosing a stage, then if a new stage is started, the telemetry data starts outputting really low or NaN values for most movements (surge, heave, sway) except roll and pitch.

-Clicking "initialize" again in the WreckfestUI window right before starting a new stage doesn't solve the issue as it keeps outputting bugged data. -Trying to close the WreckfestUI freezes the program, so it needs to be forced quit.

Only solution seems to be restarting Wreckfest, SRS and force quitting Space Monkey.

Average telemetry values during first run:

Average telemetry values after 1, 2 or multiple races finished (initialization is done right before every race): **Same stage, same settings, same car, clean and consistent driving.

Edit: added pics with the avg values after a run.
