In order to edit fields in Structure, those fields must be added to the appropriate screens from your Jira settings.
To add a field to a screen:
-
Go to Settings | Work Items. (Note: You must have admin access)
-
In the left menu, select Fields.
-
Locate the field you want to be able to edit from Structure. Click the … on the far right and select Add field to screen.
-
Select the “Default Issue Screen” for any project within the structure (or select all screens, if you use this field in multiple structures).
-
Scroll to the bottom of the list and click Update.
