AOL Mail has a serious filter-list bug that needs to be fixed.

My account had reached 383 of 500 saved filters. Without me deleting any filters, the filter list unexpectedly dropped back to 355 of 500. This has now happened twice.

The missing filters had already been created and saved successfully. Because of that, I do not want to recreate them and risk duplicate filters if they are still stored on AOL’s servers but temporarily not displaying.

Please investigate and fix the AOL Mail filter system so that:

• Saved filters remain visible and do not disappear unexpectedly.
• The filter count accurately reflects the number of filters actually stored on the account.
• Previously saved filters are not lost, hidden, or rolled back without user action.
• AOL can reliably synchronize the filter list between the account and the web interface.

This is disruptive because users depend on filters to automatically organize and block unwanted email. A user should not have to wonder whether dozens of previously saved filters still exist or are functioning.

Please escalate this to the AOL Mail engineering team and investigate the server-side filter inventory, synchronization, and display behavior.
