Can't unmute track when read automation is on

I have 18 tracks in a cubase AI 5 project. 15 tracks work perfectly. 3 tracks have this weird bug. Whenever I click read enable, the mute button lights up. When I try to click the mute button to turn it off, it toggles off and back on immediately. I cannot unmute the tracks when read enable is on. When I turn read enable back off, then I can unmute the track. I have used automation for these tracks, but nothing to seems to be out of place when I click Show Automation.

Any help or insight would be greatly appreciated.

Same problem here!!
Did you find a solution?

Guess what!
I just now noticed that the automation track the mute had on/off information in it somehow…

So i just removed all the mute data and now I’m back on track!
