How can I tell if the templates for random maps are working?

Hello. Yesterday, after a very long break, I played Heroes 3: Shades of Darkness online with a friend, and the map generated was very unbalanced. Today, I learned that this can be avoided by using templates (the Rmg.txt file). I downloaded a template I liked, put it in the Data folder (there wasn't such a file there before), and decided to check if everything works as it should. In Single Player mode, I created a random 1v1 map with the computer, setting the necessary parameters specified in the template description: size, monster strength, etc. As soon as the map was generated, I entered the cheat code to display the entire map, and what I saw didn't look like what it should be according to the template. I tried repeating it with other settings and rmg.txt files – nothing worked. The maps are generated completely differently than I expected. Could you please tell me what this might be related to (maybe the templates will only work against a human player, but not against the computer)? I downloaded Heroes version 3.58f, but I'm running it through Heroes3.exe to play the classic Shades of Darkness.
