3-Level Tree is not appearing in Scheduler

We are implementing DHTMLX Scheduler in MVC application. But facing a weird issue that is adding dynamic Tree values on the left side. We have 3-level tree in our database but we are not able to add fetch put in the scheduler. We need your kind assistance in this regard.

Please add array with sections for y_unit property that you use in your app to the demo to reproduce the issue and send me the new link. That will help me to understand what goes wrong.
