Meta Tag not on website source code

Hi all,
Did you notice that since Apr 10, the meta tag title, description and keywords that are entered under the 'setup-->website--> set-up website' in the field 'Meta Tag Html' are no longer included in the webpages of your webstore? For us they used to be included and the search engines like Google were able to read them. This information (title, description and keywords) are very important for organic rankings. Since the search could not  read them, our organic ranking dropped dramatically and so did our vistors and our sales. It took us a while to realise where that came from.
