Icon/logo/image with distinctive description...

Error:

Icon/logo/image '{0}' is being used at multiple locations within the file using a distinctive description.

Explanation:

An asset (image) can only be provided with 1 description. In this error message, the same filename has been used several times, but with different descriptions. The difference can even be a space.

Solution:

Make sure that the same file name has the same description. Find the filename in the import file and change the corresponding description if necessary.
