Email not sent to subscribers when item re-stocked, Admin also not notified.

What works, Subscription Confirmation:
When a user subscribes to an Out of Stock product. He gets a Subscription Confirmation

What doesn’t work, Email to Admin and/or Shop Manager
When a user subcribes, the admin is not being sent an email that someone subscribed for an out of stock product.

What doesn’t work, Email to Subscriber when Product becomes in Stock

Tried in a test environment, but it doesn’t work.

I thought there is some setting or configuration that i might have missed so when i checked WooCommerce > Settings > Emails > Admin Alerts
I see the alerts are active but they do not have Recepients like other core woocommerce emails have.

Please assist.
