The currency editor changes the value of the challenge cards, I'm not sure if it slot specific or if it just changes the value of "Excessive Force" only, here is a screen shot.

Interesting.
I've just checked to see if it affects any of the challenge cards I have and it doesn't seem to. Maybe it's only that specific challenge card, like you said?
Either way, the currency editor definitely does not work.
