Explanation
Unlike other Eos family consoles, where you enable and disable AutoMark as a whole in Setup, AutoMark is always enabled on the Element and Element 2 console.
You can disable AutoMark on a cue-by-cue basis on the Element: [cue] [x] {automark off}
Note: If the lights are moving in the dark on cue X, you need to disable AutoMark for cue Y, as they are referencing the levels in that cue.
