Not able to enable “Deliver Offloaded Media” using AS3CF_SETTINGS constant

As the title suggests, when I use AS3CF_SETTINGS constant in wp-config.php to set all the settings for the plugin, Deliver Offloaded Media option is disabled. All the images are offloaded to S3 bucket, but with the option to remove images from local storage on, the end result is that images are not displayed. HOWEVER, when I remove AS3CF_SETTINGS from the config file and configure all the settings manually in the console, everything works. Any idea how to fix this?
