Error message when changing language

Hello

WordPress: 4.5.2
Polylang: 1.9.1
Site: http://www.soundictive.com
Theme used: Sydney

So, I have translated my site from English to Swedish. So far everytthing is good, every page (except blog page) is translated and it seems to run smoothly. But the problem comes when i press the Swedish flag on the right corner, I get an error massage saying “Oops! That page can’t be found.”. The menu is translated and when I press on for example “about us” or “Contact us” it then works. So it looks to me as if it wont translate the header with Three Pictures I have. That is not created with a new page. Its created within the sydney theme in customize window! When you go to Settings – language – string translation I can translate the text from the main header with sliding Pictures and text.

I hope this doesnt sound complicated. Please visit my website and you will probably understand.

Thank you guys!
