Woocommerce changing labels for Products in backend

问题

I have changed the labels for products in woocommerce backend. I have used the woocommerce_register_post_type_product filter to update the product post labels.

Now I want to change the label for "Sort Product" filter to "Sort Courses".

Also I want to hide Product Data drop down which shows up when I edit the product.
