CSS Name problem (Not a freezing issue)

[Dimes]

I'm using Asf1nk's Dark Flaming Blue CSS and every time I change the names (DK to Shadow, Pikachu to Knuckles, Wolf to Lloyd) it works fine but this wierd color glitch occurs with the Dark Flaming Blue background and looks like I'm playing the game on an acid trip. The glitch also makes my CSPs near invisible which is a problem.

Can anyone provide any insight as to what the problem is and provide any method to fix it?

Thanks in advance!
