Missing spaces between words

[Volendor]

What is the problem?

Some subheadings are missing spaces.

There is also a typo like this on other pages. I would like to try to make a pull request if I knew exactly how I could fix the gh-pages.

Whatever the root cause is, it doesn't appear to be in the markdown source. Various <code> instances in the titles get the surrounding spaces removed.

It only appears on challenge block with backtick words. Search in Section 7: "Usinggrep" and "findPIPELINE". Perhaps adding more space (double space) to see the effect?
