I have a MacBook Air that the lid I left open. The screen was still on when I left it. In System Preferences, I set it to turn off the display and sleep after 10 minutes. But it didn't turn off. I know that because the next morning, all the battery ran out. Why didn't it sleep like the MacBook Air is supposed to?
EDIT: This is the result of the pmset- g
command in Terminal.

If you run following command in the Terminal app it will show you what keep it from sleeping.
Then based on the result you can take a action.
Here is a example:
In this case it was the "BoomEngine app" preventing the sleep.
In your case:
You have the "magicwake" which is keeping it from sleeping.
That could be a Bluetoot coming from headset or external keyboard(track pad), or the battery is low.
It could be also a app that you installed that would wake up on network access.
