The HTML5 User Interface available in Build 240 does not include the Cache Query Return Column Names option. This option will be available in Build 240 FP1. The option is still available in the legacy Flash user interface.
If the option has been disabled in an existing Cache Query using the Flash user interface, then it will remain disabled in Build 240.
If an existing Cache Query is edited in the HTML5 User Interface, then the option will be enabled when the Cache Query is saved. You will have to disable the option again in the Flash user interface after saving changes in the HTML5 UI until Build 240 FP1 is available.
This option has been added in InfoBurst Build 240 FP1.
