[Resolved] Copying the values from custom fields of CDX feed plugin

Problem:
The client is experiencing issues with custom fields not transferring correctly for variation products in a translating plugin and CDX feed plugin for Google Shopping, affecting pricing measures.
Solution:
If you're encountering similar issues, we recommend navigating to WPML -> Settings -> Custom Field Translation and setting those fields to 'Copy' as required. This process is detailed in our documentation, which you can find here: Translating Custom Fields.
If you don't see those custom fields, try clicking 'Show System Fields' below the 'Custom Field Translation' heading. Then, search for 'Unit Price Measure' and 'GTIN' to ensure they are set to copy.
Please remember to backup your database before making these changes.
