All in One SEO Plugin

I designed the website with word press and I am using All in one SEO but this is what it appears when I checked the site with Meta Tag Analyzer, is this normal?

Title: Title meta tag contains no errors.
This tag contains 79 characters.
Title relevancy to page content is good.
The Title relevancy to page content is 83%.

Description: Found no description meta tag.
The description meta tag is used by most of the search engines. Consider to add a description meta tag.

Keywords: Found no keywords meta tag.
The keyword meta tag is still used by many search engines. Consider to add a keyword meta tag.

What is the purpose of All in One SEO if it does not show title and description in search engines. I copies this from my index file:

<!-- all in one seo pack 1.4.6.15 [-1,-1] -->
<meta name="description" content="Wrinkles Treatment offers reviews and articles on wrinkles treatment, best skin care, anti wrinkle and anti aging products. Find the best prices for skin care products on our website." />
<meta name="keywords" content="wrinkles treatment, wrinkle cream, wrinkle creams, best wrinkle cream, wrinkle cream reviews, anti-wrinkle cream, anti-aging cream, look younger, free sample, lifecell, athena 7 minute lift, lifecell skin wrinkle cream, hydroderm, skin care" />
<!-- /all in one seo pack -->

As you can see description is there but not available for SEs, how do I fix this?

Thanks
