Getting Triple spacing after 2 paragraphs.

I'm having an unusual problem for quite some time now. Between 2nd and 3rd paragraph I always get triple spacing. In the visual editor, it shows normal but on the site, it shows triple spacing. It always happens between 2nd and 3rd paragraph only. I don't know what's wrong and can't find a way to fix it. Kindly help. For example - https://4holidaymaniacs.com/kruger-south-africa-trip-planning/ If there are 3 paragraphs without heading, this problem always happens. Thanks
