We have a custom field that's assigned to ALL request types across a project. This field works for all request types except for "service". When I attempt to "edit" an issue and use this field the "update" button doesn't process.
This is somewhat new as I have two requests that did allow me to process an update with this field selected.
I'm using Jira Service Desk 4.0.2 and Jira Software 8.0.2.
