Vehicle respawn bug?

I recently completed the “Time Attack Racer” tutorial and have started making my own race track with the blueprints. I’ve built my own jumps and everything but for some reason my vehicle slows down significantly on 2 specific jumps unless I flip my vehicle and respawn. If I crash and respawn to the previous checkpoiont before I get to the jumps, I go over them smoothly. It’s almost as if the vehicle that respawns is different than the starting vehicle.

Does anybody know what might be causing this?
