There have been reports that the player is unable to exit the 1-P Classic Mode rankings.

The issue has been confirmed and we have suggested a temporary workaround until the next Release:

1. Alt-tab out of the game
2. Tab back into the game
3. Once tabbed back in, immediately press the Ⓑ Button, or Escape Key.

We apologize for the inconvenience. We ask that you please wait patiently until the next release and/or hotfix!
