The app
 

Trying to use the app and get a boon. I am playing the super munkin. My boon was to discard a race for a +10 for me. There are no races. So is the boon I got from my app worthless? They said I couldn't use it or get a new boon.What would be the proper way to deal with it? Or is there a way to select certain things? ( like races, mojos or classes etc.)

It's been officially supported that if you roll a boon that doesn't apply to the version of Munchkin you are using, you can show that boon immediately upon claiming it and reroll to get a different one at the same Level. Here's a link to the thread regarding this matter.
