Floating barrels jump

I think I found an issue, but unsure if I’m just playing it wrong.

After the yellow train crashes into the tank, and you have to use the orange barrels to float the runway, I can’t make the jump after using all the barrels.

I used sprint and even tried using other items I found floating around.

Anybody else found this?

Crouch Jump. Argh.
