Auto Muting Glitch?

For some reason my stereo audio track I’ve put in a lot of volume automation is automatically muting itself and will not unmute unless I turn off the “read” automation button. I’ve tried making a brand new track and coping over my audio files but it’s still happening. Nothing is clipping or maxing out this seems to be a glitch. Any ideas on how to stop this? there is actually a video example of someone who had the same problem as me so you can see what’s going on, but they did not seem to post the solution https://www.youtube.com/watch?v=9B3HkLV0_Xg

thank you!

I figure this out, it turns our i accidentally hit the mute button while recording automation which then wrote it into the track, doh!
