There is a preference, fieldOrderPreference, and the fields remained on the page once that preference was deleted.
Need to clear the bad preference on the page.
Below are the steps how to clear the bad preference:
1)Navigate to your dashboard or any custom page.
2)Use the gear icon or actions button in the top right corner to Add an App.
3)Select the "Custom HTML" app.
4)Navigate to the following link in another tab or browsing window: https://github.com/markwilliams970/Rally-PreferenceDeleter/blob/master/deploy/App-uncompressed.html
5)Copy the source code from that link and paste it in the "HTML" box for the Custom HTML app.
7)In the search box on the app enter: fieldOrderPreference
9)Find the preference for the workspace you are currently scoped too and delete it for that workspace.
10)Clear recent cache and log out then log back in. Then you should see the new custom fields.
