Another GPS problem?
Hopefully not :-)
It's simply the consequence of blindly stuffing flightplan-derived routes into a lookup database without stopping to think whether the operator concerned is actually in the business of flying repetitive scheduled services.
In the case of an airline, the answer is probably yes, provided care is taken to exclude maintenance and positioning flights.
In the cases above - a military air arm (French Navy) and a corporate operator (JCB) - you don't have to be a genius to work out that they make up flight numbers as they go along and you can't reliably translate those into routes.
