convinced this double set's bugged & qdo query

Speaking with a member Buck here on this thread (https://forums.ea.com/discussions/skate-en/please-more-forgiving-ways-to-land-big-tricks/12727259/replies/12907944) who shared a video doing the double set in the attached image in playtest and got huge pop. Said he cant do it since, ive tried and also cant clear this set. Its not a speed issue video of my attempts below, I could only clear them with a kicker which is lame.

Other big sets the game seems to recognise you're going for stairs and gives a huge pop that carries you far and high, like the first double set in my video https://www.youtube.com/watch?v=18j5f9Aowdk

The second double set does not, maybe a skill issue on my side but convinced they're bugged.. feels like the game doesn't  recognise them as a double set and will only let you do one at a time. Sucks having to give up on a trick.

Every big set i've tried so far is skate-able, this one seems not. Maybe someone can prove me wrong, otherwise hope a dev sees this and fixes.

Also as a side note why are random players able to move your qdo? that should only be for people in your party, everone else should only be able to disable.. so many randoms messing with the things you set up
