I have a custom field called "Stakeholder" that is required in two projects and on four screens. It WAS working until I had to create a new stakeholder field because we needed it to be a multi-user select. Now, the new Stakeholder field won't hold an assignee.
From the Create screen, I add myself as the assignee. Once I go to the issue, my name is gone and I have to re-add there.
I copied all of the settings from the old field to the new field so I'm not sure what's missing.
