Retargeting ANimations for Mixiamo Model

Hello right now trying to retarget my Mixamo model to work with Animation Starter Pack, But I am running into a problem. I have set up everything correctly, so far from what I know. Yet, I think I know where the error could be. I am thinking it deals with the “roll bones” like the “lower arm roll bones” (so far I believe they mean wrist). For the Mixamo model has no bones like that. I tried applying the hand bone to the lower arm roll bone. But it still comes out looking like this picture. Dose anyone know how to deal with this. Thank you for your input and time.
