I've been copyright striked

Jun 26, 2019

I received an email sent at 8:15am about one of my scores "When You Wish Upon A Star" being taken down for copyright infringement.

To be specific, it is my arrangement of the song for piano from the Disney movie Pinocchio. The licensing under this score is "Attribution" due to the fact that it's my arrangement of the song and I do not want anyone to claim the specific arrangement as their own, not the original song itself. The reason I am bringing up the licensing is because I'm not clear on whether the copyright strike is because of
1) my score is based off a popular song
2) the incorrect licensing
3) or a software glitch (as mentioned by Mike in another discussion post on this forum)
If it's possible, I can always change it to public domain. This is my first time receiving this notice, so I am unaware of what exactly happened. I'm hoping this can be settled and one of the staff members can take away this strike and make my score public again.

Also if anyone can educate me about whether I did the right thing about licensing my score as "Attribution" I'd greatly appreciate it.
