Did you edit the description words? Edit the homepage, you will see Yoast SEO panel: https://www.dropbox.com/s/lze7sal634j5czu/QQ20180306-094238%402x.jpg?dl=0
If you have changed it, maybe there is cache https://kb.yoast.com/kb/my-meta-descriptions-arent-showing-up-in-the-search-result-pages/#cache
If it doesn’t work, please send your question and wp-admin(url/user/pass) via
my profile contact form (you need login on ThemeForest), I’ll log in to check it.
