Problem importing multiple languages with Falang

-- HikaShop version -- : 4.0.2
-- Joomla version -- : 3.9.2
-- PHP version -- : 7.3
-- Browser(s) name and version -- : Chrome

I'm building a multilingual website with Hikashop. I have a working installation of Falang and I can manually translate the products. But when I try to import from a CSV the import does not split into multiple languages. Below is a small portion of the csv import file which isn't working. When I import the product is not updated or changed. Could you tell me what the correct syntax for the csv import is?

"product_code";"product_name,product_name|de-DE,product_name|en-GB"
"C001";"Truffel,Trüffel|de-DE,Truffle|en-GB"

Thanks!

I added every translation in a separate column in Libre Office with the correct heading. That was the trick! Then the export will work.
FYI:

Column 1 with: product_code
Column 2 with: product_name
Column 3 with: product_name|de-DE
Column 4 with: product_name|en-GB

Thanks!
Thanks!
