Improper shoulder rotation when retargeting

Howdy,

I imported a Daz3D character after pushing it through 3DS Max, to get rid of some stray vertices.

I then retargeted the skeleton, which seems to work fine, except for the rotation of the shoulders. As you can see in the image below, the Daz character does not rotate her arms down properly. Everything else moves to where it is supposed to be. Any thougts?
