I need to bold few words in a texfield.

For example,

below are my XML

<paragraph>"Join with <b>Adobe enterprise products</b>. Access a vast library of learning content and <b>courses</b>, get personalized recommendations, and <b>connect with a vibrant community of fellow learners</b>".</paragraph>

And I change the field format to Rich text. But that doesn't help

I  was expecting for something like below. 

"Join with Adobe enterprise products. Access a vast library of learning content and courses, get personalized recommendations, and connect with a vibrant community of fellow learners".

But All I got is 

Join with <b>Adobe enterprise products</b>. Access a vast library of learning content and <b>courses</b>, get personalized recommendations, and <b>connect with a vibrant community of fellow learners</b>

I can only bold the entire text field.
