Problem with Time attack racer tutorial

Hey guys. I was following the Time attack racer tutorial and I reached the part with setting up the checkpoints :

I seem to have followed it perfectly except for the fact that I’m using my own static mesh vehicle instead of the vehicle in the video. However, I can’t seem to get the checkpoints working. When my vehicle passes through the trigger volume, the trigger box is supposed to disappear but it doesn’t. What could I be doing wrong? I have attached a picture of my checkpoint blueprint.

i got the same problem, did you solve it?
