Nuxeo 5.6 DAM, import images with Administrator user (also happens to anyone) and there aren't previewed. No error in the trace.

If we click to Document Management, we see that they had been created. If we try to preview them, nothing appears. Error trace:

 - Property not found: picture: views / item [0] / content. segment 0 can not be resolved ...

Certainly, reviewing exportXML, this metadata, it is not filling…

Please HELP
