Corrupt Cache is improperly displaying Custom Fields in Project Professional

The wrong custom field values are displaying in the Project Professional client. PWA is displaying the values correctly.

Verify:

1. You have the same SP applied to the client and the server(s)
2. Clear the cache on the client machine:
a. Run the command %appdata% in the Run dialog.
b. In the Application Data dialog, navigate to the folder Microsoft\MS Project\Cache.
c. Delete all of the files in this directory.
