Problem with project always opening on "blog" page

I’ll try to make this as clear as I can. I have just finished a bilingual site (Japanese/English) and every time I open the project it shows the “blog” page.

at the top.

this is the top English navigation

on a closer look, all pages have /blog/en/html. The following is the navigation for “Mission Statement” on the site. But it reflects on all pages.

I have tried exporting the project and when I open the index.html file

all is good. The index file is linking correctly to the “home” link. And for all other pages for that matter.

Can somebody please tell me why "each page is showing the “/blog/en/html” at the top and is it ok to just upload to the server without any problems?

Thanking you.
