When a staff people go into the Update Code Table screen they only see what was added by the district and a list of the existing codes in use on the right column (without any descriptions).
It would be better to display all code values on the screen and those that are hard-coded have a lock icon, are dimmed, or something showing they cannot be edited.
If that is enabled, allow a filter to hide those hard coded codes as an option displaying only the district added codes.
This prevents the need to go to the reports screen and run a report for the specific table if someone doesn't know the code values and/or descriptions.
