toggles not always working right

I have created two pages with many toggles. The problem is randomly one or two of the toggles will not often work. If I refresh that page it will then work but a different one will be broken. Is there anything I can do to correct this?

Pages can be viewed/tested here:

How can I make a toggle which says "read more" say "read less" after it has been opened up?
