There is a bug that causes some map script options to change other map script options, when there are more than 9 options total.
See this thread for details - download links for a map script with 12 options are in the first post, the description of the bug and instructions to reproduce it are in my post #12. I have tested it also on other map scripts, so it's not specific to this one - it's a general bug in the game.
