[تم الحل] Discounted variable product price

Background of the issue:
I added a discount price for the product T4E45CAM80100, but it is only showing in the original language (Estonian). When I try to add it manually, there is a message saying it is locked for editing and WPML will copy this value from the original language. The issue can be seen on this page: الرابط المخفي.

Symptoms:
The discounted price is not showing in the translated language. Instead, I see the regular price.

Questions:
Why is the discounted price not showing in the translated language?
How can I ensure the discount price is copied correctly from the original language?
