Null String error

[Trifler]

In Star Wolves 3: Civil War, when I open the drop-down menu for any of my characters (the one that says: Team Leader, Attack, Defend, etc.), the space for Anti-Missile Defense says "Null String". I can tell it's Missile Defense because it has the icon and I remember from the first two games.

Also, everywhere I go in the game, my Mission Log displays a "Null String" as one of my objectives. It doesn't seem to hurt anything, but it's weird.
