Multiple unique names are being used within the article groups

 
 
Error:
Multiple unique names are being used within the article groups.
 
Explanation:
In the case of the translated article import, all article names that exist in 1 article group must be translated with the same translation. As soon as different translations occur for an article name within 1 article group, this error message will appear.
 
Solution:
Make sure that all article names (Article name) within 1 article group (same number in Article group ID) have exactly the same translation.
