Implement drag and drop function Angular TreeGrid error

I checked the drag and drop function of Angular Treegrid from Syncfusion document website some month ago and it work fine:
However, now, when I really implement this function to my website, I got error, the control seam to redraw the row every where when I drag. When I check the link again, I get the same error. In the console, the errors happen every time I move the mouse.
Anyone got the same problems?
Thanks
