Strange behavior in Navigation Pane Designer

jemmy

I can’t select object type = ”Table Data” (although it is displayed by option button) while updating Menu Item Property in the Navigation Pane Designer. It always becomes blank.

I also found a strange behavior. If I create a new menu item, the option button will display 5 strings (Table, Form, Report, DataPort, CodeUnit)

But if I update the menu item, it will display 10 strings (TableData, Table, Form, Report, DataPort, CodeUnit, XMLPort, MenuSuite, System, FieldNumber)

Anyone could advise what is going on this Designer? Thanks in advance.
