Performance Timer bugs

It only works when I use the same car. Whenever I choose another car by changing the current one via the vehicle selector, it stops working. The only way I found to make it work again is to remove the timer and create another one, which is annoying when trying to compare acceleration differences between cars.

 

It happens after I reset and swap the car
For example, when I do a 0-60 test after getting the timer app out, it will count normally. Then, I reset the car and swap in another one. When I do the 0-60 test again, the timer doesnt record the time anymore.
