Eureka Mignon Filtro Metal Shavings in Coffee Grinds. : Coffee

I bought a Eureka Mignon Filtro I started off at the courses setting and dialed it down to the finest then dialed it back halfway between the finest and coarsest setting while the machine was off. This morning I woke up and turned the machine on to grind coffee in the medium setting and got several small fingernail thick metal shaving. I took the grinder apart cleaned the burs and coffee residue from the grinder, reassembled, and still found two metal shavings in the grounds this morning, although significantly smaller and less frequent than before. I was wondering if anyone had a similar issue and if there is a fix?
