Html Code in Classifieds?

I didnt really do anything different to my classifieds that I know of, but for some reason when I look at classified ads on my site, theres this section under each ad(when you click on an ad) that says HTML Block and has all the html under it (with countries and some other stuff). Below is a screen shot of one classified ad. Anybody ever seen this before or know how to get rid of it or what its for? Thank

do you use tinyMCE like this below picture?  if yes, you need to click "html" button and insert your html on that .

if not , you'd better see your code and place this function before your output

.

process_html_output($your_output);
