I have implemented a few changes on the site, including that of adding another plugin to add meta tags. As it appears, for some reason the Yoast plugin was adding a meta description for articles and posts, however it never included authors or page descriptions. Weird.
The page was re-crawled today and all of the Meta Tag errors are gone! Hooray! Now I just need to work on the super long titles that the writers before me used.
Thanks for the help to all the took the time to post!
