Re the copyright stuff - it could be that your performance strongly resembled another piece already copyrighted. You should be able to submit an appeal since it is your own performance
It says “video uses this song’s melody” where the song is the piece I’m playing (at least presumably - it just says Flute Concerto in D Minor and doesn’t mention a composer), and it’s a composition claim so I think it’s literally BMG Rights Management (US), LLC, ARESA (yes I copied that from the bit that says who the copyright owners are) are being a bit shit. The other hilarious bit tho is that it’s not the whole piece, just the last two minutes (feat wrong and cracked notes lol) so idek what is happening.
