Combination of Mixamo Animation Causes Crossed Arms?

Hi guys! I've been doing a lot of googling and youtubing but I still have not been able to find an answer on how to fix this. Whenever I try to combine mixamo animations, I always end up with the model getting her arms crossed.

 

Everything looks fine when I import both the main fbx with my model and the other fbx without skin. However the second I use the other fbx action on the main armature, the arms get crossed.

 

(Additionally, if anybody can let me know how to have the second mixamo animation to start at the position the last animation ended instead of blinking back to the main starting location , that would be great!)
