When the genetic algorithm used in the genetic optimization phase produces a chromosome that is invalid, it technically has an infinite cost. This cost is reduced to 1 for the purposes of evaluation and graphing. This typically appears when genetic optimization of prediction inputs is being used and an offspring is produced which has no inputs enabled.
