Text not wrapping around image

Hello, I’m having problems with text not wrapping around images. I didn’t use to have this problem before the update. I noticed that when I use just plain text, the text will wrap but when I add headings to the text content, it doesn’t.

Here is what I have:

<h3>A Whole New Form of Marketing</h3>
<img class="alignright wp-image-352 size-full" src="http://www.mariadelamo.com/wp-content/uploads/2014/06/infograph_4513_362460-e1403621003889.jpg" alt="Marketing Science" width="328" height="783" />With the Internet, businesses are taking on a whole new form of marketing. And now, due to new eye-opening marketing tactics, we're starting to view marketing as both an art and a science. There has and always will be a science to marketing, yet at the same time, there's an art to it that only true marketing professionals can master. According to Stan Woods, an employee of Velocity Partners, he refers to today's marketing specialists as both marketing artists and marketing scientists.
<h3>Learning and Understanding Consumers Like Never Before</h3>
Today's marketing specialists --whatever you want to call them-- are taking advantage of technology in a revolutionary way by pleasing consumers and earning customer loyalty. Cloud-based programs are giving them access to Big Data in real-time, meaning they are able to track, quantify, analyze and enhance their marketing endeavors like never before. Because of this, we're truly learning the ins-and-outs of consumer marketing and what it is that consumers want in a product/service.
