[تم الحل] WPML Export and Import

Background of the issue:
I am trying to do a multilingual import with products on my site الرابط المخفي. I followed the YouTube video 'WPML Export and Import - The multilingual solution for all WordPress import plugins' (الرابط المخفي).

Symptoms:
The products are not mapped to the right language after running the export and import. I imported 10 NL and 10 EN products, but after the process, I have 10 NL products and 0 EN products. The total number of products is 20, but 10 are not accessible or connected to the English translation.

Questions:
Why are the products not mapped to the right language after export and import?
How can I ensure that the products are correctly connected to their translations?
