Walkthroughs for custom maps.

How is this possible? Where did they come from if they aren't in the folder? And how can I delete them? Because of them, I can't play maps that aren't displayed.

User Marmot already suggested: "The file names of the standard maps are all in English, even for the Russian versions. Maybe that's why?". I'll just add that since the game takes the name from the map itself and not from the file name, you will see them in Russian.
