Adaptive Engines seem now language variant dependent?

Hi!

I understood that AdaptiveMT engines were language variant independent, while now, maybe after the SR1 update, if I create a project with English (United Kingdom)- Italian (Italy), the baseline engine works fine, while my two adaptiveMT engines are no longer selectable and display English (United States) - Italian (Italy).

BTW in my SDL Cloud account my two Adaptive engines are listed as English-Italian, without specifying language variants.

Is there anything I can do to get back all the work done with my AdaptiveMT Engines, and to be able to use them in a variant independent mode?

Thank you!
