removing the woocommerce postcustom metabox

version: 3.1.1

File: cargo-shipping-location-for-woocommerce\includes\cslfw-admin.php: Line 21

Question for the developer:

add_action( 'add_meta_boxes', array( $this, 'remove_shop_order_meta_box' ), 90 );

In the callback function (line no:283)

//remove meta box from the admin order page
public function remove_shop_order_meta_box() {
remove_meta_box( 'postcustom', 'shop_order', 'normal' );
}

Any reason for removing the woocommerce postcustom metabox ?

We found it cause issues in existing plugins.
