Emails sending for deleted variations.

I am doing a spring update for one of our manufacturers and twice now when I deleted all the variations on a product page an email was sent to a customer who was subscribed to a variation that no longer exists.

For example we have a page for jerseys. This jersey came out in 2020 and the listed variations are no longer current – a redesigned model is now out for 2021. I delete all the 2020 variations and an email gets sent to a customer out saying “Product (#XXX) is back in stock!” with no Product Name or Variation name listed. The add to cart link does not work as this variation has been deleted.

The plugin should not be sending emails for a deleted variations or products…
