Blend Shape issues - @Alan

So trying to sort out my blend shapes on the patches and every time I edit them on the right-hand side of the body they don't seem to be updating. The left side has been fine, tried to mirror over to see if it would copy, but that hasn't worked either

Example

So editing the mesh, like I did on the other one.

But when I move the keyframe back to the natural position, however, I have edited it now seems to stay natural position. IT doesn't seem to shrink or grow, it stays however its been edited.
