Props displaying as Errors instead of the prop.

Hi!
I am working on a map for making a scene for something, but I am having an issue where the props won't display properly in TF2.
They display correctly in the Hammer editor, but after compiling and running, it causes the props to appear as errors, or not appear at all.
I have images attached to this post to give an example.

What would be causing this to happen?

Hi!
Yeah, sorry I forgot to include it.
Here is the compiler log.

Hi!
That worked. I just of somehow forgot that prop_static is the way how to put props down correctly.
My mistake
