tobiasjingfei on "[Plugin: WordPress SEO by Yoast] SEO Yoast update changes my post display,help."

I really need help.After updates of SEO Yoast,,my blog display changes a lot.Now my blog posts list page shows the whole post instead of short paragraph.(http://www.wax-strips.com/blog,please scroll down to check this problem)Also in the detailed post page,the display is incorrect.
All the posts displays before the plugin update are correct.
I did not make any change in the template code.I am sure it is plugin problem,since I have two websites using the same template.Both of them have the same problem after Yoast update.
Relly need help!
