Only the first animation thats imported, works

NewVision

I use DAZ Studio 4.7 and try to import animations from a poser pose file.
It works fine, when I import it, the first figure is animated correctly.
But when I import another animation pose for a second character, only the keyframe 1 is imported.
I tried to find settings for that - I can find no solution.

Funny is, when I used DAZ 4.6 soon after installation, this importing worked correctly with the same files.
Is there a bug in 4.7? Or is there a preference setting I need to change? Or something else?
