blank space between poll and Opinion Stage signature

Hi guys,

Great pluguin, just what I needed. Althought I have a issue.
I’ve installed and added a poll into a page, no problem with that. BUT: there’s a enormous blank space (like 4 paragraphs) between the poll and the signature “online poll by Opinion Stage”. This is the page:

Thanks a lot!
