Garry's Mod Spacebuild 3 errors

Hello,

So I recently bought Garry’s Mod
After a while I decided to download These addons: CAF, LS3C, LS3E, RD3, SB3, SBMP.
So here’s my problem:
Whenever I spawn a ship, let’s say the SBEP Carrier SteakKnife, and step inside the ship, i start getting these errors all the time:
Error: Function (EndTouch) not found! on Scripted Entity (sbmp_carr_steakknife)
Error: Function (StartTouch) not found! on Scripted Entity (sbmp_carr_steakknife)
Error: Function (PhysicsSimulate) not found! on Scripted Entity (sbmp_carr_steakknife)
Error: Function (PhysicsUpdate) not found! on Scripted Entity (sbmp_carr_steakknife)
Error: Function (EndTouch) not found! on Scripted Entity (sbmp_carr_steakknife)
Error: Function (StartTouch) not found! on Scripted Entity (sbmp_carr_steakknife)

And the same list goes on and on…

If I spawn something else from the SBEP ( for example blast doors), I get the same errors…

Anyone know how to fix this?

Thanks!
