Feature '{0}' is being used with a distinctive or empty icon at multiple locations within the file.
Explanation:
If the HeaderIcon is filled for one feature (Header), the same HeaderIcon must be present everywhere for each unique feature (which can therefore be used for several item groups) for all article groups to be imported.
If not, the article importer will give this error message. The specified HeaderIcon is stored with the feature in the Header table, so that each feature can only process one value. For all article groups (from the import and in the already existing article groups in EZ-base) where the feature is used, the icon is shown instead of the name. By including the HeaderIcon column in the import file, but leaving the value empty, you can remove the icon from the feature and the name will be displayed again.
Solution:
Look up the relevant features and adjust the value for the HeaderIcon column everywhere to an equal value for all articles in the import file with the relevant feature.
