why page builder synces same (info) template when creating bilingual pages

I am creating a bilingual website (English and Chinese). After i used page builder to create a page in English version, i was excited to change the Chinese version with the relevant page. But the thing is that Page Builder synced the English page info/template and I cannot change anything for Chinese page…Otherwise, the English page would be change as well… Could you please let me know how to deal with the problem? Million of thanks!
