[Plugin: Canonical URL's] WordPress SEO

I installed WordPress SEO last week. The only problem notices as of yet is as follows:
When I go to Dashboard, choose Post/all Post. All the titles that should be displayed have the letters lined up rather than left to right ( normal reading for American English). The alphanumerical charcters, referred to by me as letters, are lined up one on top of the next.
This makes reading the titles of the post almost impossible to read.
