Neutral units not showing up

This is really starting to bug me. I created 15 neutral hostile units, and 15 neutral hostile heroes. In the object editor, they are both in the same category, but the heroes are in the heroes category and the units are in the units category. For my spawn trigger, I want to spawn a certain amount of the neutral hostile units in a rect. Here's the problem. I make a trigger, and use the create units facing angle action. I change the 1 to a 15, click the zergling default, and go to change it to my custom units. I go to the neutral tab, and custom. Only the heroes show up, and I look in every category with every possibility, and my units do not show up in the trigger editor. So how am I supposed to fix this?

Ignore this, I'm a tard and figured out the problem.
