Membership Plugin and WPML

I have Membership Plugin activated and translated into Chinese language, however with the WPML it's not really working properly. In the Membership Options section where I specify Register, Welcome, Account ... pages, it only works in English frontend page (through WPML), but when I change into Chinese page it's empty.

Vice versa, when at the Chinese language Dashboard, I enter the Membership Options section and specify the chinese verson of the Register, Welcome, Account... pages, at the frontend, only the Chinese pages are working, but not the English pages.

At the Dashboard I see see, that when I specify these pages at Options under English Dashboard, these pages will dissapear under Chinese Dashboard Membership Options and vice versa.

Please help how, thank you!
