Error Updating Highend Theme Version: 3.8.8

The latest update of the Highend theme to Version: 3.8.8 caused all the body copy text (paragraph size) to decrease in size on my entire site including posts and pages. All other fonts (H1, H2, H3, H4, etc.) remained the same size. I am the only one who works on the website, so nothing else was changed except for the update to the theme.
