Blocks html code differs between languages

I've noticed that Translated blocks are being treated differently to "original language" blocks. For example, one block on my site, the content in English is rendered with <p> tags by Drupal, but the translated Korean language content is missing the <p>.

See in the top right hand corner there is an address? This is a block that I have added to the header section in "Blocks". The content is translated into Korean using the language interface.

Example (www.jpguitarland.com.au/drupal-6.10/):

English data:
37/160 Rowe Street, Eastwood NSW
Phone: (02) 9858 3210
Fax: (02) 9482 1003
E-mail: skhjames@jpguitarland.com.au

Korean data:
37/160 Rowe Street, Eastwood NSW
전화기: (02) 9858 3210
팩스: (02) 9482 1003
이메일: skhjames@jpguitarland.com.au

You'll see that neither of these has a <p> tag, but I find that in the final code that Drupal renders, the English version is wrapped in<p>, but the Korean version isn't.
