Private Dashboard and Filters Not Viewable by Global Admins

One of our JIRA users, who is not a global admin, created a new Dashboard and about 4 new filters. He did not choose to share the Dashboard or filters so I assume they are private. He wanted to share his dashboard and doesn't have that permission when he "edits" the dashboard. Therefore, as a global admin, I logged in and was going to share the Dashboard for him. However, when I search for the Dashboard it's not found. When I search for the filters he created they are also not found. As a global admin, why should those be hidden from me?

I also had another of our global admins test this and he is having the same experience I am. I'm not sure where to go from here.
