Thank you for your question. The data for this demo is set as the inline JSON in HTML, that is why there is no reference to it after the report is saved. If you want to have the ability to restore the pivot from the report you should put data to separate JSON or CSV file (for instance, look at this sample – http://jsfiddle.net/flexmonster/rkprvhhs/).
Please, let us know if it solves your problem.
Thank you for reporting.
There was an issue on the website, now it is fixed and you are welcome to check the demos.
