Smart essential mode help

I just got the Enduro a couple days ago after upgrading from the pro 3. The trouble I'm having is the Enduro will go into essential mode when I go to bed, the problem or at least what's confusing me is that it'll also just completely turn off. When I wake up the lcd isn't on, is there a way to stop it from turning off entirely, or is this a malfunction of the watch?

Update- I tried just altering the factory set time in which it's set, & it's stopped turning itself off completely & just goes into essential mode with no issues (so far).
