When I go to the Data Source (first) tab, there are "0" data source filters. But when I click add my own data source filter, I see four action filters in the data source filter list and after I add my filter, the data source filter then shows 5 as the total data source filters (the four before plus mine probably). These seem like phantom data source action filters. Can someone tell me about these? My numbers are not matching a replica of these same filters. How can I find the source of these action filters?
Hard to tell without seeing your workbook.
My guess is that you've specified the data source as the target on a filter action.
