In defining an Alert, the expression drop-down has "ANY" and "ALL" and I am assuming that this is in regards to the if statement portion. However, for the if portion you have radio buttons, so there really is ever just one expression, so "any" and "all" doesn't really make sense.
Nevermind, I am tired. Closing
