Vermilion prop protection not working?

So i’m running a dedicated server running Vermilion server manager and for some reason when i turn its built in prop protection on people cant phys-gun there own props! So i tried what most people would do which is turn it off and install FPP (which i like better anyways.) and when anyone spawns a prop Vermilion spits out an identical error twice and the prop becomes public so anyone can pick it up.

[Vermilion2 - Server] Warning (Entity [505][prop_physics]): prop owner was overwritten by CPPI!

heres one of the errors.
