Unable to change power settings (Windows 10)

I'm getting an error:

*Some settings are hidden or managed by your organization.

The steps I took were:

1. Open Group Policy Editor (Win+R, then type "gpedit.msc")
2. Navigate to Computer Configuration-Administrative Templates-System-Power Management
3. Double click the Specify a custom active power plan policy setting
4. Set to Disabled
5. Click Apply then OK

I was then able to change my power settings. Not sure how this got out of whack but this solved it for me.

Other things tried: 

Running "powercfg -restoredefaultschemes" in cmd as admin
