Dalaran Heist Class Completion Tracking is Broken

As an avid solo adventure player, I have been working my way through winning as each class on each chapter for the various modes. After the patch yesterday, after winning with a class on one chapter, the crown now appears above that class for the rest of the chapters. This has completely derailed the tracking of my progress for both normal and heroic. I hope that this was not Blizzard's intention from the beginning, as I enjoyed the individual chapter progression.
