Retargeting animations in motionbuilder

Hi there,
I‘m working on retargeting animations from Unreal third person FBX ( A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

). I made my character in Daz studio and exported it with rig. Everything works fine except for retargeting arms. Motionbuilder says : The right arm doesn’t seem to be parallel to the X axis. The left arm doesn’t seem to be parallel to the X axis. I tried to change rotation etc. but nothing works for me. Do you have any idea what can I do with it?
