We assign classes to our employees which is the customer they work with.  We hired a new employee about 6 weeks ago, and have been processing payroll for her.  I just ran a report and realized she was placed into a brand new class that I did not create, her own name.  I did not get the "you must assign a class" error message that I usually get upon setup, and instead her payroll got put under this new class.  I've assigned her to the correct  class now, but how do I fix the paychecks already run?  In the past when I've switched classes on an employee, I remember I would get an option to make it retrospective.
