issues with lap check and respawn handling

i am following a tutorial by the name “time attack racer” to understand more about blueprints. in the 7th video “lap display and respawn handling”, the objective is to display the number of laps completed and also to respawn the car if it flips. issues i faced while doing this:

  1. the lap number doesn’t show up at the top left corner
  2. when i flip my vehicle, it still moves a little bit(yes, even when it is flipped). maybe that’s why my vehicle doesn’t respawn.
    i m currently using unreal engine 4.10.4
    is there some problem with the in-built vehicle blueprint?? help!
