1) How is this a problem?
2) DC doesn't care. They sabotaged Cass for the sake of Babs and don't seem to wanna stop. Cass' book outsold Hawkman, Catwoman and Firestorm's when it was cancelled. All three books have since gotten second and/or third chances, while Cass got shafted with a mini series written by the guy who screwed her up to begin with.
