Disabling RouteDebugger in administration site

I just upgraded my code base from 2.3 to 2.4 and I see its using RouteDebugger. This is great except that I cannot disable it in the administration portion of the site. I've already set the RouteDebugger:Enabled to false in the web.config for Nop.Admin and rebuilt but this has no affect. Is there any solution to disable it other than completely removing the reference to the assembly and the config section?

We found duplicate RouteDebugger:Enabled settings in the main web.config after the upgrade with conflicting values. Simply removed the duplicates and everything is fine now.
