Actually, if I just click on update for the page (without changing anything) the false disappears and the icons can be seen on the page.
Another thing that I noticed is that the Sociable disabled check box then becomes checked and there is nothing that I can do to uncheck it. If I try to uncheck it, the next time I click on Update page it gets checked again.
I noticed that the icons had disappeared on the pages where they normally appeared. If I go to the sociableoff custom field I have to remove the ‘false’ from value and leave it blank. Then the icons will appear.
This had shown the icons with ‘false’ before. I will hold off changing anything for now.
