UE5 Retargeted Anim BP distorts skeletal mesh

Hi, i am trying to retarget ALS animations to UE5. IK Rigs for ALS_AnimMan and SKM_Quinn were made and a Retargetter that connects the IK Rigs. Inside the retargetter the ALS animations are correctly shown on the Quinn IK Rig. However when i then retarget ALS_Anim_BP using the retargetter and assign SKM_Quinn as Skeletal Mesh inside the retargeted AnimBP, the mesh gets scaled up enormously and it looks very twisted and distorted.
Maybe someone could give me a hint on what causes this and how to fix it?
