Hi.
I've inherited admin for an old Jira, and I've noticed that issues in several projects, once their status is set to DONE, they still have the resolution "Unresolved". As an example, one small project has 77 issues as DONE, only one is "Resolved", and it's from December 2018. Every issue after that is marked as "Unresolved" which means they show up in the "Open issues" filter since it filters on "resolution = Unresolved" instead of "status != Done).
So what I'd like to figure out is this: is there something wrong with the workflows? Anything I can do to fix this permanently?
