If I click in one of my projects in Jira I am not able to see my issues:

If I click on "View all issues and filters" I can see the filter by default that is not working with my configuration by is: project = BIO AND resolution = Unresolved ORDER BY priority DESC, updated DESC
I have realized that the problem is with the term resolution = Unresolved
Is there any idea where the problem could be?
I had resolution field hide but I have tested to unhide and it is still not working.
Also I have been testing the state "Resolved" but configuration is the same as Jira default configuration.
Thank you!
