Enabling units in skirmish

[Athanasios]

Simple question, might already answered but whatever

 

I have a small problem with making some new units buildable in skirmish. To be more precise, ive enabled TIE Advanced X1 as buildable unit in GC (with text description etc etc), set it to Tech 2, but it will no appear in skirmish.

 

This is an example, but im intending to import Imperial guards too, so, i might run in the same problem...

 

So, how you enable units to be buildable in skirmish?

 

Thanks in advance
