DarkRP guns bug?

Hello, I updated my darkrp to the newest version (2.3.7+), I have set a server with DarkRP, but guns shipment, and pistols cost 0$, when I type commands what set the cost of them, they are still 0$… Anyone had it, or know how to fix it?

Any idea?

Its a bug. Falco is away currently, so is therefore unable to fix it.
