How do I Delete Track Mute Automation?

by mistake I left overdub turned on while I was muting tracks, now the tracks are muting automatically during playback. how can i get rid of this?

any help is appreciated

sorry, nevermind, right under my nose in step edit.

a quicker way is to push the erase button, its often already set to 'erase track mute' (esp. after doing an overdub in my experience). then just press 'do it'
