wp_content_foldername gets stripped in wp-config.php

Hi Corey,
I’ve encountered a problem duplicating my local wordpress instances (I’m using xampp).
My installation uses a subdirectory for wordpress core files and a custom directory for wp-content. My wp-config.php looks like this:

define('WP_SITEURL', 'http://localhost/mylocalsite/src/'); // my wordpress installation
define('WP_HOME', 'http://localhost/mylocalsite/');

define ('WP_CONTENT_FOLDERNAME', 'data');  // custom wp-content folder
define( 'UPLOADS', ''.'files' );  // custom wp-content/uploads folder

define ('WP_CONTENT_DIR', ABSPATH . WP_CONTENT_FOLDERNAME) ;
define('WP_CONTENT_URL', WP_SITEURL . WP_CONTENT_FOLDERNAME); 

I#ve never had any problems but in recent versions of duplicator the foldername definitions get somehow stripped after duplication:

define ('WP_CONTENT_DIR', ABSPATH . WP_CONTENT_FOLDERNAME) ;
define('WP_CONTENT_URL', WP_SITEURL . WP_CONTENT_FOLDERNAME); 

becomes

define ('WP_CONTENT_DIR', 'ABSPATH');
define('WP_CONTENT_URL', 'WP_SITEURL'); 

Actually no big deal to manually adjust the wp-config.php but in previous versions those lines have been preserved during the building process.
Any Ideas? I have to admit, that my custom folder definitions might be quite clunky or deprecated.

Thanks for this indispensable plugin!
