Why does the GPO setting for "Disable Developer Tools = disabled" not take effect when mozilla.cfg "devtools.policy.disabled = true"?

Our organization currently runs FirefoxESR versions and uses mozilla.cfg to control some lock down that are not available using the GPO. Below is the setting in question: 

     - mozilla.cfg 
            lockPref("devtools.policy.disabled", true);
     - GPO deviation setting
            Computer > Policies > Admin Templates > Mozilla > Firefox
                    Disable Developer Tools = Disabled

When the computer updates the policies and users launch Firefox, Developer Tools is missing as an option. Below are the results after gpupdate /force: 

    - about:config
            devtools.policy.disabled > locked > true
    - Registry (regedit) 
            HKLM\Software\Policies\Mozilla\Firefox
                  DisableDeveloperTools = 0

THANKS Everyone!

I'm a little confused by what you are trying to accomplish.

Are you trying to disable developer tools via Autoconfig and enable them via policies?

Because you have DisableDeveloperTools set to 0.
