I have a working Decision Tree having a data object whose edit functionality works fine when we try to click on the circles. I want to add another Decision Tree for a different Data Object but when I try to edit the circles(root object/other objects) in this scenario, the edit functionality does not open a pop up. There is no java script error either. Now I try to add a different data object to the new decision tree but still the edit functionality does not work.
I have moved this decision tree and data object to a different package as well as to a different project. But still the edit button does not open a pop-up. Neither the close(X) button or collapse button work for these circles.

Attaching the snapshots where edit functionality of one decision tree works and it does not work for other.
