If you need to replicate the only 1 role to all subsites you may go to the main site of your network and open User Role Editor there. Select role – ‘editor’ in your case, turn on needed capabilities, turn on ‘Apply to All Sites’ checkbox at the top:

Then click ‘Update’.
‘Network Update’ button in the User Role Editor at the ‘Network Admin’ center fully overwrites all roles at all sites by the roles from the main site.
