How to I remove the word "uncategorized? from my main blog page?

To Whom it May Concern,

I am using the divi wordpress theme. On the page where I have all of my individual blog posts list, below the title of each blog I see the word "uncategorized." I would like to remove this word so that the only things showing below the title of each blog post is the author, the post date, and number of comments each blog has received. Strangely, when I click on an individual blog post, that is exactly what I see: the author's name, the date that the blog post was published, and the number of comments that blog has so far received. I would like exactly that same type of setup below the title of each blog post on the main blog page. Could you help me do this? Is there a way to achieve this with CSS?

I look forward to your response and thank you in advance for your time.
