Clicking on repair doesn't solve the issue (not clicking either). I tried different datasets and still have same issue.

It looks like this might be an issue with the Javascript / Flash bridge that your example was using. If [I use the HTML5 export button type](https://jsfiddle.net/51cuxtto/3/) it works okay. Your example wasn't using that as it wasn't including the JSZip files (so it was falling back to Flash).\r\n\r\nAs a workaround for the moment, perhaps don't include the Flash buttons in your application and use only the HTML5 export options?"}}
