Media Player Timeline - Meaning of Blue Event Coloring

I use multiple Media Players (for MIDI/Audio Tracks) and while editing many songs in rapid succession, one of my Audio Tracks turned blue and it stopped tracking with the Master Player (MIDI Track). I’m thinking that the Blue May indicate some change has taken place, but it remains after setting the Playback Length and saving the song (ALL actually). I finally had to delete the non-tracking Media Player and build another. Unfortunately, the Blue remains. I obviously did something while editing the songs, putting plugin info in my spreadsheet and dodging my music cats! Might someone have an idea what I’ve done? Thank you!

Not exactly sure what you mean by the Audio Track turned blue. Do you just mean how the waveform data is highlighted blue when it’s selected? Or something else?

Can you post a screen shot?
