Stuck in Tour 2: Bag of Tricks (The Next Level)

I'm stuck on the mission where I need to do a 2s grab at the SVLocs hangout ramp, I'll clear the gap with a 2.5s+ grab and land cleanly and the game isn't registering it.

Slappy says "I guess that's a decent enough score but no grab - rebate" 

So I'm just stuck in this mission and can't progress. Help pls 🛹
