Sticky Posts in WordPress Can create problem sometimes

I wrote a post about IlistIndia and make it sticky post. The decision was good but that same I noticed another problem on my blog’s homepage, I was unaware why the problem happened. I have set 10 posts on homepage of techshali but it was showing 11 posts, one extra post was at bottom looking like a patch. I was thinking to ask about it in Thesis forums or search on Google about the problem. After one week today I made that ilistindia  post no sticky and the problem was solved then I knew what was casing for 11th post on homepage.
