Used DazToBlender, moved some verts around. Now retargetted animations broken

I have a Daz model that I’ve brought into blender using the Daztoblender addon, which was quite painless. It’s fully rigged and ready for animation, including shapekeys.

I wasn’t too happy with the position of one eye and eyelid, so I moved those verts back, say by a distance of “X”. I pulled in an animated mixamo character, and used a retarget addon to send the animation data to the Daz model.

Everything works fine, except the eyes and eyelid, which are now moved forward by a factor of X. Whatever change I made to the mesh now appears in a different direction. Any idea what could be happening?
