I had this exact same problem and contacted support. I was told to add this snippet to my functions.php file and it fixed it.

add_filter('woocommerce_order_query_args', 'th9e_woocommerce_order_query_args', 99);
function th9e_woocommerce_order_query_args($args){
    if(isset($_GET['page']) && $_GET['page'] == 'thwecmf_email_customizer'){
        $args['type'] = array('shop_order');
    }   
    return $args;
}

I recommend reporting the issue to the developers of the plugin at?https://www.ads-software.com/support/plugin/visualcomposer/#new-post

It’s not a Visual Composer specific issue. It happens with other plugins with the same file structure. Happens regardless of an update or a fresh upload.

Same issue here, I’ve had to temporarily resolve it with a javascript hack.

The error should be fixed by adding a required hash to the field like it does with the normal fields, but the extension fields don’t seem to validate the same way as the normal ones
