I agree with Gayle - I'd never have thought there was a problem until you pointed it out!
I don't know of a way to remove fusible either. Is this something you can live with? If you can, I say just let it pass. It's possible the fix will end up looking weird.
If *I* were going to try to remove fusible, I'd re-heat it with the iron and see if it could be peeled off. No idea if that will work and might leave residue and weirdness behind, though, so I'd say make a plan "B" for covering up the area if that looks bad. Maybe applique a white or light green circle over the whole area and put new berries & leaves inside the circle? Sort of like an ornament?
