我am.gettont NaN和#SCL类型的值在我的dhtmlx树网格中

I am.gettont NaN and #SCL kind of values in my dhtmlx tree grid

I am trying to load data in my dhtmlx grid. For some data the grid displays NaN or #SCL kind of values and for others it's proper values coming from database. Can someone please tell me where the issue is if someone might have encountered such kind of situation.
