Initial Unit spawn problems

So I'm making a map with custom units, and I want a main defense unit to be available in certain countries, but not others. However, upon testing to see if it worked, I found that the countries where I set it to exclude from spawned with these units. I cannot build these units, however.

Well that's not very helpful.

Bump for a legitimate question.

U would have to do it all manually as turn 1 events
