You could modify the git bundle to not set the scope for modified files, but I think you're better of customizing the theme so that those colors do play nice.

To change the theme you open the bundle editor, (Bundles -> Edit Bundles...), select the bundle containing the theme you're using and select the theme under "Themes". Now search for "markup.changed", there you can set the foreground and background color.

Is there a way to change or remove the added/removed/modified backgrounds in Git Commit Message?

Looks like predefined colors don't play nicely with every theme out there.
