Exporting animations do not match Editor animations

I've been trying to export some simple animation clips.

Two of the four exported animations do not match the ones in the editor.

I have tried both generic and humanoid animations and the both have the exact same problem

The arms in the animations in question begin in the T-pose. Which isn't even close to the animations in the editor.

I know humanoid retargeting isn't perfect, which is why I also tried generic animations and they didn't work either.

I've tried exporting to FBX and Anim file and it happens either way.

Again, two of the four animations have this issue while the other two work just fine.

I have no idea what is going on. I've spend hours trying to figure this out. I'm lost.
