Shared calendars on Huawei

Hello,

I'm trying to sync shared calendars on Huawei P8-Lite, with Android 6.0.
I've enabled sync of theses calendars via ZxMobile Sync Zimlet.

But i only see my calendar, not shared calendars. I've trying to use Mailwyse, but no changes.

How can i show shared calendars ?

Thanks !
