This isn’t happening for me when I visit, but as yours is a commercial theme, it’s best that you ask the developers about this.
I have asked on their forum, not received an answer yet, but it’s interesting it doesn’t happen when you visit. Very odd.
Maybe just a different browser or version, or browser cache on your machine, hard to say. I hope they can help you out via the theme forum though. Good luck!
You’re welcome. BTW, while you’re waiting on a response in the other forum, you might try disabling plugins to see if one of them is involved in this.
