R1 means you won it in a challenge. K means you won it playing Kongai. ST (or something) means starter and S means special edition, which i have no idea how you get.
quote Portal-
"You can't reset your cards on this game, they should have a button that has this function. It's good, but not very good 'till I/we can reset our gameplay, just in case you messed up, and want to start fresh again."
