I am developing a gantt chart using Telerik's Kendo UI for JQuery. I am using the Material css theme. If I add a Summary Task with a single Milestone Task within it, the Milestone Task displays as a diamond but the parent Summary Task is a Task of zero length which cannot be seen:
I have seen examples where a smaller diamond is depicted for the Summary Task. I checked the dates for the Summary Task and the Start and End are identical. Am I missing something here please?
