Workforce Planning | Invalid Column Name

I'm receiving the following error when trying to add additional Register Definitions.  During the build, I've added new Register fields as requirements evolve but now am facing this error when running the Update button.  Has anyone run into this issue and resolved it?

Invalid column name 'Location'.
Invalid column name 'EmpStatus'. (SQL Error Number -2146232060, 207, 207, 207).
