I've been trying to figure this out for the past 3 hours and I think I made it even worse
I'm taking over a new project in JIRA and the Resolution field is not updating when tasks are completed. All tasks say "Unresolved".

The currently workflow is the simplified workflow set up by the previous admin,
Open --> In Progress --> Internal Review --> Done
I am hoping to have the Resolution field to change to Resolved whenever it goes to the Done status. Can anyone help me?
I updated the workflow trying to resolve this issue, but instead, I think I just accidentally added 2 Resolved statuses into the workflow and after publishing it, I'm not sure how to revert it back to the original workflow. with just the 4 steps?
Thank you to anyone in advance who provides any comments or feedback!!!
