First, let me express that I hope that everyone from AIG and elsewhere is healthy and the Coronavirus pandemic has not seriously affected anyone that you know personally.
My suggestions may also be somewhat of a question. What I have noticed that even if I set up the name of a non-AIG flight plan using the same naming convention as the AIG plans use:
Airline_Author_Season_Year.bgl
the AI Manager does not display the season and year in its flight plan list. It's a minor problem, but an additional result is that for the few newer non-AIG flightplans, even though they are for 2020, they show as OUTDATED.
please upload the BGLs of the flightplans, I will check why the generic parser is unable to read them
Attached a few BGL files that don't display season and year. Also at:

Note, one of those non-AIG plans that I included has a v2 on the end of the filename and the version displays correctly.
