Plugin removes order actions

I found a small bug. In order-details/en-puro-small-order-widget-details.php the plugin uses woocommerce_order_actions as an action, but in fact it is a filter for order actions. So the en_assign_order_details_pruo_smll function should return the value passed to it – right now it doesn’t return anything and because of this the order actions dropdown on the order page in the admin panel is empty.

You can also (and personally I think it is a better solution) use add_meta_boxes action, because this function only adds a new meta box.
