Scenario:
On a website, the item description is showing on the PDP page coming from the field “Sales Description” from the item record. The same field is available under the translation tab and it has value for different languages, But still does not translate while changing the language from the website.

Solution:
This issue may due to the Sales description field is not available under the web store tab in the item record, so we can use either the ‘Featured Description‘ or ‘Webstore Description‘ (ID: storedescription) fields instead of the sales description on the PDP.
In the website configuration record, we can change the field ID under the tab ‘Shopping catalog’ and select the Product Details page sub-tab.
