The internal names for the traits that are responsible for the seleucid reforms are BeatenByCats and ImpressedByCats.
Regarding the character names: I suspect you tried to give the trait to someone with a triple name? Those names are dependend from traits and don't equal the internal character names that you have to use for the console commands.
I don't know how exactly those names work for the seleucids, try to use characters with only two name parts, if you still have some of them.
