Sidebar Posts

Good Day, I am building a website for our company, here is the link http://www.new.wintandkidd.com.au/, I am having a problem with the posts, because everytime I select the posts in the website, there is an annoying sidebar that is appearing as seen in this link http://www.new.wintandkidd.com.au/2015/03/10/dont-miss-our-next-event/,

all of the services that is listed in my website always showing at the posts but not in the pages,

Thanks, any help will be deeply appreciated
