Name of the article group has been modified, but the import does not contain the complete article group.
Explanation:
The name of the article group has been modified, but the import file does not include all articles in that group. Therefore, the name change cannot be implemented because articles cannot be included in this change.
Solution:
Expand the import file with the missing articles from the group in question and ensure that the name of the article group is the same for all articles in this group.
