Polylang and WPAlchemy – Can anyone help me please!?

Hi there to all. I am new in this puling And I think it is excellent but difficult to start (as always with a new translation plugin)
I managed to configure it propperly, but no matter what I do or funtion I write I am unable to duplicate meta fields created with WPALCHEMY.
Can Anyone please help me to duplicate WPALCHEMY meta fields with POLYLANG please?
