Font formatting on WPLMS theme Home page

I accidentally deleted a text box in the Page Builder of Home page (before I actually understood how it worked), and to replace it, I just copied and pasted text from the block next to it. The problem is that, no matter what I do, it won’t display the same…even though the formatting is exactly the same.

How can I make the 4th box display like the other three…here’s a screenshot Admin access is granted through the WPMU Dashboard.
