Show in Repository shows you the location of the model in the repository. I suggested you use that in order to understand where the model comes from ... no change was intended.
Regarding the image display (barcode) issue, I presume the reason it originally stopped working is some change you made to the example. If you have re-imported the original, and are still encountering issues, you might be encountering a browser cache issue. Try clearing the browser cache and retrying.
If it's still not displaying, try another browser, and if it's still a no-go, you're welcome to export the model you're using (File>Export>Tersus>Tersus Project File) and attach it to a reply, with instruction on how to recreate the issues.
For best results, use the Firefox browser..
