All of a sudden, site builder has conflict with Polylang.

I am using Polylang 2.2.4 and Site Builder 2.5.13 and the theme is OnePress 1.4.3 by FameThemes. I used these combinations for a few sites I design before without problem. But all of a sudden, whenever I created a page with the site builder and use the Polylang to create a translation page, the site builder will copy itself to that translation page instead of giving me a fresh blank page. Whatever I do in one translation page it automatically mirrors to the other translation page as if they are the same one. I deactivate all other plug ins except Polylang and site Builder and it is still do the same thing.
