Why are some of my images the same as another image on the template instead of the images I uploaded?

On Interactive Designer templates the file names must be unique. When two or more images are uploaded with the same file name the system will generate the production pdf off of the final image uploaded. For example if I have a template and upload two different images named "family.jpg" The second image named "family.jpg" will appear in both image fields when the production file is generated.
