duplicate ISBN for kindle and paperback editions

[Marcelo]

Hello! I've come across a Portuguese paperback edition of the book "Transcendental Style in Film: Ozu, Bresson, Dreyer" and I went on to add it here on Goodreads, but the ISBN had already been added for the Kindle edition. There was no cover so I decided to edit it anyway.

I'm wondering if I can add the paperback as another edition with the same ISBN, or if I should change the Kindle edition to the paperback. If I can only use the ISBN once for one edition, I think the paperback should take precedence...

What do you guys think I should do in this case?
