Seeking Help With Parameters Table

[racha]

I've modded some edits to the Parameters table that work, setting my preferred levels of resources, world age, etc, but I'm completely at a loss as to why some other changes don't work. Specifically, I want to set the default difficulty to king, map type to pangea, map size to huge and turn off the score victory / turn limit.

The part I'm having the most trouble understanding is that the difficulty and map type/size are definitely being changed in the database:

And yet the setup menu isn't reflecting this (DB screenshot was taken while in the setup screen):

Can anyone suggest how to fix this? Here's the code that's not working:

UPDATE Parameters SET DefaultValue = 'DIFFICULTY_KING' WHERE ParameterId = 'GameDifficulty';
UPDATE Parameters SET DefaultValue = 'DIFFICULTY_KING' WHERE ParameterId = 'PlayerDifficulty';
UPDATE Parameters SET DefaultValue = 'MAPSIZE_HUGE' WHERE DefaultValue = 'MAPSIZE_SMALL';
UPDATE Victories SET EnabledByDefault = 0 WHERE VictoryType = 'LOC_VICTORY_SCORE_NAME';
UPDATE Parameters SET DefaultValue = 0 WHERE ParameterId = 'MaxTurns';
