VNR134 Duplicated Flightplans

A P180 operating as VNR134 flew into KGAI last night, and remains there now. The same flight number (usually designating the same a/c registration) is shown with multiple flight plans filed to make the same run in a few hours. What causes all these duplicates?

I’ve seen a lot of duplicates over the last couple of days, but not a full page’s worth.

Wow, that’s special. They filed every day for a full week in the future.

Looks like someone accidentally made a “canned” flight plan for the aircraft. I flew for a freight hauler that had scheduled legs, and all our plans were stored and automatically filed for each day. Looks like that’s happened for this aircraft.
