Multilingual site

Site URL: https://charge4go.com

I found a guide to make my webpage multiligual, in English and Swedish.
https://www.bradgood.net/articles/multi-language-content-on-any-squarespace-template

It should hide the second language navigation links when using one language. For example when on the english page, you see the english titles, and when on the Swedish page, you see the Swedish titles/links. 

However, it seems that:

1. The nav links disappears in the burger menu when looking at the site on your phone.

2. When on the Swedish (svenska) page, the english links/titles are shown. 

The only nice way i found to choose language, is creating a language link in the footer. I tried to create the flags as shown in the guide, but it did not work..

I'm not good at css, and don't know how to fix this. Can someone please help me? 

Hi.

Can you share link to a Sweddish page?

Which code did you added? Can you paste all here?

yes, and it will cost you as much as your squarespace plan or more. I don't think that's a fair solution
