Route add/edit page

Hello

I am trying to override the editor.php page after enabling this in the settings, adding CMMRM directory to child theme, and copying the editor.php into it as per directions. Within the editor.php, I am trying to add further code for information to be displayed, but upon “add new Route”, this information doesn’t show. What then is the purpose of overriding the editor.php file, if it doesn’t actually override?

All I use the CM Maps Route Manager Pro plugin for is to upload my own GPX files to display a route on a map, and bundle those routes together on one map canvas for users to select and download the GPX for. Could I use this plugin solely for this purpose without it generating its own Route custom post pages? Or, at least change the editor page to only display the fields I need/own information I need, rather than all the items shown?

Thank you
