I am trying to make updates to some dashboard report filters and they are not being saved and/or are somehow holding on to previous settings.

For example, if I change a setting in one of the dashboard Sub-Reports, it is not reflected in the Dashboard that this report is part of.

Also, I have a dashboard where I have removed on of the tabs that contained a report that I was having trouble updating the filter on and even though I deleted the tab and the corresponding report, the report filters are still somehow showing in the dashboard Parameter Values.
