We have a lot of old data in these tables from deleted dags, which are still sitting there and slowing page load when we click on security permissions tab. Is there any way other than deleting from database tables?
ab_view_menu
ab_permission_view
ab_permission_view_role

So the root of my issue is that I have a task group with several tasks, once in a while one will fail and that will set the status of the task group to failed instantly instead of waiting for all tasks to finish.
