I did run a couple of updates recently; I’m not sure if that is related and now I have to configure something differently.
Under Theme options if I turn on Portfolio projects AND set Portfolio page to my “How to Use” page then I get a 2nd grid and not one that matches the style that I created in the XStore Portfolio Grid builder, so I have that turned off at the moment.
The problem relates to WPBakery Page Builder and is independent of the theme. The plugin authors will fix it in the upcoming update. Once the new version will be available officially for download on codecanyon, we will update WPBakery Page Builder on our site – https://www.8theme.com/downloads/
