Use the "what links here" tool and you can see what uses the one template. Only a few dozen pages, mostly in one timeline.

Just about none of your "no" boxes for the one template are actually true. Most of those are in the template, or not actual problems unless you screw up naming the article in the first place, like you did.

Imo, it looks like you didn't actually look at the template for any of the lines for those features.

As for the "before" and "after" countries, it's called the "former country" template.

Your template looks horrible too, with regards to color.
