Invalid Ship Style Detected

Hello,

My Galactic Civ III game has a number of custom races that were designed by other people and installed on the game.    I always get several pop-up windows which says: 

Invalid Ship Style Detected
The Ship Style [name] has failed to validate for the following reasons and will not be available:
+ Unknown Ship Class
[DONE]

Now if the game assigns some default ship class as a result, can it not remember this for the next time the game is loaded ?  I get several of these pop-ups when I start the game and each time the same pop-up is displayed.

Can't whatever the default replacement choice was be remembered so I don't get those pop ups over and over ? 

If there is no fixing the value, how about an option to unsubscribe from the custom race that introduced the problem, so that it won't re-occur later on ?

Thanks.
