Unwanted DownShifting After Unpausing the game

I play Motorsport on Xbox Series S and I’ve noticed that Whenever I pause the game while holding full throttle (automatic transmission) and unpause the game while still holding Full Throttle the Car will Shift Down immediately and shift back up again. this is costing me a lot of time on my laps.
This bug occurs on any Track in any car at any time I pause and unpause while holding the throttle down.
