Thanks for your feedback!
I have just checked your site and that’s seem you added custom CSS code: http://prntscr.com/klfiif
Please check the first red box where you added this and it’s cause this issue about font.
Hope this help!
The bad news is that i haven’t added that code in the first box ANYWHERE!
Your reply doesn’t help much.
I am attaching a screenshot with the code on that page and the visual composer options.
Please check some more!
