The 3-letter world name description

[raz92]

You know when you enter a description of your world in Visualmunge so it's supposed to show up when you select your map in IA, well mine just appears as MFM%s_%s instead of "My first good map". Does anybody know the solution? And yes, I have entered the discription in visual munge. And I get an annoying problem when playing my world. When the small tool tips come up on the bottom of the screen, it's [NULL] instead of the actual tips, and when I kill an AI bot and it's supposed to say "Blah killed Gamma 321" or whatever, I also get [NULL]. I will be very greatful if anybody know the solutions. Thanks.
