DarkRP Shipments fall through props

Im not sure if this is the right place to post this but on my darkrp server the shipments fall through props and i cant find out why.
If any one knows how to fix or why this is happening please let me know.
Also i tested the exact same gamemode in single player and it doesn't do it if that helps.
