Grid export to Excel doesn't export sub-grids

Is this a known bug or am I doing something wrong? I’m using the Dhtmlx PHP server app - although I’m passing the request through our Django app to a private php server because we love Python :mrgreen: .

Everything else looks good and also tried PDF with same results.

Thanks for any info,

Just to add we are using DhtmxlPro Suite 3.5.

Unfortunately the export of the subgrids is not supported.
