Since a few days a scheduled report builder report shows empty charts regularly. When i refresh the data in the excel file manually, the lines show up again. Does anyone has the same experience? What can i do to fix / prevent this?

Just tried it. Amazingly it worked out, seems to be a new feature. Thanks for pushing me to try it again.

I asked Customer Care more than one year ago. This feature of removing or editing tags does not exist. Once added a tag, it will never go away. So finally i'd really appreciate the reqested feature.
