You can search/replace using an text editor in the XML to replace T_SLIDER_EffectBlur with B_SLIDER_EffectBlur
That said, we need to go through the SS and other importers and remove all of these entirely. The C_/T_/B_ panels now all do NOT output any keys that are defaults. Thus, if the import needs the defaults, it should just not output them. I'd like to do the same with the E_ keys, but that's a bit more work. However, it will make the XML files quite a bit smaller and also make the rendering (very slightly) faster.
