Revoking "direct share" access to dashboards

Question / Description: When I open a dashboard and view the "Access list" modal, I see several users who have access granted through "direct share", but I can't revoke their access.

The access list modal has a link to "Permission Groups" (, but that page doesn't let me revoke direct share access either.

Where do I revoke this access? And is there a single page where I can audit direct access to every dashboard we have in our account?

Update: I think this is a visual bug on the Access List modal, because at least one person who's listed as having Direct Access to that dashboard doesn't actually have access.
