So I debugged this and realised that before the second elements where added to
the ValueList the lists were cleared and reset to empty lists. So when the next
element is added the list is set to the default value which is true. It appears
in subsequent rounds of adding new children to the list they are again cleared.
I have added a debug trace to show where the list is cleared and on the next
iteration where the lists are all set to true. I'm not sure how to fix this as
the code makes a call to osgSim::MultiSwitch::removeChild which clears the
list. Not sure why the code is calling removeChild.
Some of the line numbers may not align with current OpenSceneGraph 3.4.0
version as I have added some logging into it.
