[Plugin: FV All in One SEO Pack] Google Verification Meta not showing on home page

I have added the meta tag info copied from Google Webmaster Tool under the Advance Options tab on the Setting page. After clicking on the Update button, Google said the site couldn’t be verified and the meta tag code was not listed in the source neither. While I “hand put” the code into the header file, I wonder what did I do wrong here. The home page is a static page on the site under the Front page displays setting, by the way. Thanks.
