Default Drupal breadcrumb translation problems

My breadcrumbs have some problems in multilingual setting. My site has two languages are Vietnamese and English.

I have the menu “Services” which is translated to Vietnamese is “Dịch vụ”. And one content in it has the name “Content” – translated to Vietnamese “Nội dung”.

When I access to English site and go to the “Services/Content” page, it appears “Dịch vụ / Content” instead of “Services / Content”. What I’m trying to say is it appear “Vietnamese / English” instead of “English / English”.

Hope to receive some helps from you guys. Thank you very much!
P/s: I checked the translation but I don’t see anything goes wrong 🙁
