[General] Tech Tree Requirements/Research Level Requirements Bugged?

[SerenityInFire]

Hey all, so I've run into a little problem with my map. Instead of the townhall upgrading to keep upgrading to a castle and whatnot to advance to the next tech level in my map, I have a research that advances the tech level. It goes Age of Enlightenment, Age of Magic and Age of Wonders. Now that that's out of the way, my problem is this: The armor and damage upgrades for my units also have multiple levels, which each level requiring an advancement to the next age. The problem is, it works for the level that requires Age of Enlightenment, but I'm able to advance to the next levels of my armor and damage upgrades without advancing to the Age of Magic and the Age of Wonders. I've added values to the level requirements for each level of my armor and damage upgrades, but it doesn't seem to work. Is it bugged, or am I missing something? It works fine for a tech that's only one level that requires the Age of Wonders or something, but it just doesn't work with these techs that have multiple levels.
Here's a screenshot of the editor so you can see what I'm talking about.

I just tried to get this working in a test map with a slew of different combinations and it does, indeed, appeared to be broken. Or, you have to do something janky to get it to work right (which I couldn't figure out).
