Category of {0} with value {1} has been modified...

Error:

Category of {0} with value {1} has been modified, but the import does not contain the complete article group.

Explanation:

The asset category with a certain value (image, logo, icon, etc.) has been changed for the article group to be imported, but the article group is not complete.

This means that there would be articles with the old and the new asset category in the same group. This results in this error message.

Solution:

Make sure that all articles from that article group are also in the import file.
