[Resolved] After updating translation I'm missing product sizes

Background of the issue:
I tried to change the product title on the translated site using WPML. After updating the translation, I noticed an issue.

Symptoms:
I'm missing product variations on the updated product. Disabling the cache plugin and bulk updating the product didn't resolve the issue.

Questions:
Why are product variations missing after updating the translation?
How can I restore the missing product variations?
Is there a specific step I missed in the translation update process?
