duplicator page on site homepage

Hello.

I tried installing a new website using Duplicator.
But I faced something weird.

After installation was completed, I tried checking every single page, and on all pages I see Duplicator Step #1 wizard on header part.

You can check the website using the link below :

https://demo.karamicar7.com/

Any sort of help is appreciated.
Thanks
