Spinning circle when trying to access field select list after upgrade to 7.3

Behavior:
After an upgrade to DocuWare version 7.3 or higher, when trying to configure a select list for a field you are met with a never ending spinning circle.

Solution:
This is due to Select Lists not processing properly during the upgrade. In order to fix this please do the following:

1. Open your "Indexing Assistance" module
2. Go into each select list and click "Save" where the button is active and applicable
3. Go back to your file cabinet field and configure select lists, the spinning circle should now be gone.
