the When any Switch.getfocus block, does not return the name of the component that received the focus; The block that should have the name of the component is marked with an X in a red circle, clicking on this block shows the list of global variables.
I've checked other "Any component" blocks and they seem to have the same bug unless my interpretation of the operation is incorrect.
Show your blocks screen shot.
Not sure the get focus blocks actually work for the switch component. I know they work for textbox.
