How do I fix distorted metahumans after animating them?

I’m animating my metahumans in the sequencer and they keep distorting and glitching. I’m using UE 5.5 and I can’t find the settings this tutorial is referencing. The wrists are stretched and one of them has shoulders turned inward.

If it helps I also created new sockets in each metahuman so they could be holding tools during the animations, I don’t know if that affects the way they’re animated or move too much.

Does anyone have any suggestions?

Thanks
