For other articles in the article group the '{0}' column for feature '{1}' is filled, but not for this article.
Explanation:
An article always has its own article number and features. It is not possible to process articles with and without HeaderHidden, HeaderInSpec and/or HeaderIndex within an article group. If there are both lines with and without values in these feature columns, this will result in this error message.
Solution:
Make sure that for the articles within a group the reference columns are filled or all empty. Then re-import the file.
