Delete a Class fails with "pyWorkClass is not a database column"

Hello, I'm using Pega 7.1.9 and have run into a problem while trying to delete a class from a specific Application using DesignerStudio > System > Refactor > Classes > Delete a Class.  I've used this wizard to delete several classes from two other apps, but when I try it with a third app it skips straight to the "Done" page when I enter the class and click next two times.  By looking at DesignerStudio > Application > Tools > All Wizards, I see that the wizard is stuck in an open state.  When opening the wizard it states that there's a flow problem and gives the following error:

Work Object pxW-XX has encountered flow problems in DeleteClass.

The flow DeleteClass of type DeleteClass has encountered a problem on step UITILITY53. Property 'pyWorkClass' is not a Database Column.


I used the tracer when i clicked "Next" in Delete a Class and noticed that the FAIL's first show up when getting to step 17 of the pzAddWorkDataHandles.  This step looks for a History- class of the app you want to delete.  In the database I can see that History- tables exists for the two other apps that let me Delete Classes successfully, but no History- table exists for this third app that won't let me delete.  In addition, pyWorkClass is a column name in those two classes where Delete a Class worked.

I'm not sure where to go from here to fix this, or what caused it.  Is there a reason why no History- table exists for the app that's not working?  Do I need to create one somehow?  Any advice would be appreciated.
