I've seen several threads about the need to have a status in the Resolution Field in order for a closed ticket to be considered truly closed.
I've also seen a number of members suggest we simply remove the "RESOLUTION" field to avoid having duplicate statuses or tickets that are both open and closed.
Given I'm only learning this now, and now I already have closed tickets with empty resolutions, I need help on HOW to close those tickets and go back update the resolution field to get them to show closed/crossed out in the backlog.
