Back in Stock and Price Alert for WooCommerce

Hello,
In variable products, the subscription notification comes twice. Once, as usual in every product, and a second time if the size was selected. While both are signing up for the product in general and a particular size, they look unprofessionally redundant. Once the size (attribute) was selected, the first signup notification should be removed automatically. Also, that doesn’t make much sense to show the price subscription in sold-out or backordered products. If possible, please fix these ASAP or add the checkbox in the settings to control. Thank you
