Thank you for writing in, it seems you did not configure your font families, please navigate to Font Manager and define the font families that you want to use.
And then navigate to Theme Options > Typography and set the BODY FONT and HEADINGS FONT from the font families you defined in the Font Manager.
Regarding the Dropcap, please apply a padding-bottom to it.
Remember to clear all your caching features (plugin, server-side, CDN, and browser's cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope it helps,
