I have a Lyrics track with chords and in the track name, I have [yellow] [chords:red}.
Both the lyrics and the chords show in yellow. Chords do not show in Red. This is true whether or not I have a +CC in the track name.
I just tried to reproduce this on my end, but with a track called βLeo +LYRICS [yellow] [chords:red]β, lyrics are yellow and chords are red as expected. Do you have any custom styles by chance that might be overriding the color of your chords?
