Alembic in 0.7.5 issues

Hello,
I am trying the new alembic support and have found a couple of issues.
I first imported an alembic file that is baked as separate objects (a character that is not a single mesh) It shows up fine, had to scale it up, but only a single part on the character actually plays the animation the rest just stay still.
So I figure maybe the alembic has to be a single mesh, so I exported the character as a single mesh and imported back the alembic but the animation wont play at all.

Any idea what am I missing here?
