css - Text appears cut off on top -

I have a problem and I do not know how it happened. It was good one day and the other in my lesson, there is a cut at the top in that column.

This is the website, and the problem is on the right column in the title :!

Definitely what this is, but you can do some things

  .text-format h2 {margin-top 1px; }  

Or it also works

  h2 {line-height: 1; }
