Background of the issue:
I use a filter on "_stock_status" in WooCommerce that returns the value: in stock, out of stock, on backorder. I'd like to change the translation "On Backorder" to "On Backorder/Preorder" but I don't know how to do it. I tried using the "String translations" and even Loco Translate but it's not working.
Symptoms:
Unable to change the translation of "On Backorder" to "On Backorder/Preorder" using WPML's String translations or Loco Translate.
Questions:
How can I change the translation of "On Backorder" to "On Backorder/Preorder" using WPML?
