I have a license to manufacture destructive devices (type 10 FFL), but based on the form instructions destructive devices do not need to be reported. Should I stop filing?

No, a license to manufacture destructive devices also authorizes you to manufacture firearms, the production and sale/export of which must be reported. Even if you produce only destructive devices, the filing requirement still applies to you, and you must file a report and reflect "0" (zero).
