Some sections do not have multi language function

Dear,

I use your plugin and SKT themes (http://sktthemesdemo.net/hotel/). My website is http://rosol.vn/demo/. I can do multi language with the post, page, category, menu. However, some section (section 1 to section 6 on the homepage), I can’t do like this. It doesn’t give me option to enter multi language. I mean it just give me one option to write the content. And it display one content for all language. You can see it on these links bellow:

Could you give the idea to solve this problem?

Thanks,
