Toggle Shortcode Glitch

Some of my toggle shortcodes show too much white space on the front end, see http://jurassicfields.com/discography/
I guess it is an incompatibility with one/some of the text characters.
Can anyone shed any light on this for me please?

Hello,

I'm sorry, but i'm not sure where the white space is exactly. Could you give me a screenshot with this element marked?
