Misspelled Words in Comments

Hello, I noticed the words in comments on my blog post are missing the lower case letter "i" Here is the URL http://everythingiswine.com/why-men-should-drink-more-wine/ This just happened today after updated my Jetpack plugin and approved two new comments. The words are spelled correctly on the back end where I go to approve the comments, but for some reason they are misspelled on on the blog post page. Any idea what could have caused this? Thanks, Tivon
