Sunburst Chart - Hover Data/Rendering

Hi Folks,

I have some issues in rendering my sunburst chart. It contains 4-5 layers and lots of segments. It shows the strange behavior, that in my hover data, some segments show all data correctly, however some show no values, just =(?). The source data is valid, all segments stem from the same table. Can this happen if the sunburst chart contains too many elements due to the DOM limit? If so - any idea or tips what I could do to solve this issue? Would be great!! Thanks!
