/trails command not working

[Cucumber]

I just bought the particle effects from the /pointshop and I tried using the /trails command but it doesn't work. All it shows is a stupid message. (and yes, I am 100% sure I have bought it)

particles are different to trails. Particles can be used when playing in buildwars and can be used as decor. While trails give you awesome wings

How do I get trails, then?

EDIT: Nevermind, I'm stupid. I found it.
