Hi team!

I am trying to build a website using Onepage template. But my menu is not working properly.

1. I have 6 menu items.
2. Home item called "Vitajte u nas" is green becasue it's active.
3. Hover is working
4. I click on another menu item, example contact "Kontakt".
5. Page will scroll to desired section BUT menu item is not higlighted. Higlightes/Active is always the first home one. How can I fix it?
6. Also smooth scrool is not working.

I probably changed or removed something after the instalation of quick package but I don't know what. Can you help me?
