1) Create a data object and create variable Map<String,Object>. 2) Create a rule test scenario and add that data object and add the map variable and try to double click on insert value ans it will not show any pop up, but if we add like    Map<String,String>.then it will show pop up and you can add key value pair. 3) I have created a reproducer(using Map<String,Object>.) and attached it along with screen shot. If you make changes in a reproducer like using Map<String,String> then it will work.
