This happens if you're using one of the macros more than once inside a post/page. Say, your page looks like this:
[bibsonomy-tags]
... some content ...
[bibsonomy-tags]
[bibsonomy-chart]
[\bibsonomy-tags]
The output of the first macro will show up but the content until the closing part of the same macro will disappear.
Solution: just add the closing part of a macro to every macro on this post/page.
