Can’t copy ACF fields.

Hi,
I have problem when copy ACF fields to the other language.
Deactivated all plugins except WPML and ACF. changed theme to twenty seventeen.
I’m using WPML and ACF Pro lastest version. But when I’m trying to duplicate page from NL language to EN language. But no custom field get copied.
When I try to export all ACF field and import to other site. It’s still can copy all fields. I think problem at how data saved in database.
I have contact with ACF support and they tell me: “it sounds like there is a problem with the WPML pugin when trying to ‘translate’ or ‘copy’ the post meta.
Can you please contact the WPML developers and ask for their help.”

Thanks for help.
