WPML product translation not available in vendor dashboard

Hi!
I′ve a marketplace runnig on WCFM (ultimate + grous&staff) installed and translated with WPML.
My problem is that vendors can′t translate their products on their dashboards… there′s no option (see image froma a vendor product editing page: https://ibb.co/V9gdHW0).

I′ve another issue: if a vendor creates a product from the dashboard in a not-default languaje, it′s created in that languaje… ok, that′s perfect, but after creting it, the vendor can′t edit all the meain product features ′(as the new product is a translation) and he can′t translate it also… so it is imposible fir him to edit or change anything on the new product!!

Thanks in advance.
