I'm going through the same thing with two songs on YouTube. Never happened before.
It is ridiculous. The melody and lyrics are totally different, only the chord progression is the same, and they can't own a chord progression. The company creating this mess is: Associated Production Music LLC.
The chords are from a BIAB Bluegrass Demo. There was no melody or lyrics on it other than solos and I didn't use any solo lines for my melody. Here's one they're trying to take from me.
