Imported bone transform is different from original?

I haven’t been working with UE4 all that much, but previously I have been able to import and implement animations on skeletal meshes that I made myself. But with this new mesh, I’ve been having issues importing animations. Maybe I’m doing something wrong and I’m just being an idiot, but I can’t recall doing anything differently.

This is the message I recieve when I try to import my animation. I have not made any changes at all to the skeletal mesh, just animated it and exported from Blender. When I try to preview the animation, I see a tiny version of the mesh, almost impossible to see, playing the animation, but it’s stretching quite a bit. Any ideas on what I might be doing wrong? Any help would be greatly appreciated, thanks!
