filters not persisted after restarting fiddler

If I add a filter to hide something like /teams-modular-packages/ after closing fiddler classic and opening new file filter shows as active but is not working. I need to explicit remove filter and add it again. I would understand that filter wouldn't work accross sessions if filters were removed but they aren't and always showing in bottom left corner. This can be easily reproducible. (in this repro i have imported HAR file, not done a live capture)

This is an (undocumented) limitation of the Quick Filters feature -- it runs all of its processing inside the FiddlerApplication's RequestHeadersAvailable event. That event isn't fired for Sessions that have been reloaded from archives (or imported).

I'm not sure what the right approach here is -- arguably, you might not WANT filtering applied to a capture by default. Maybe there should be a way to "Re-run all filters now" available by right-clicking on the Filters text?
