Deformed Leaves On Dahlias ?

For the first time this year I decided to grow some dahlias. I planted them in my raised bins. All but two came up. I have noticed a problem with some of the leaves and can't quite figure out what is wrong. Perhaps someone else knows? The photo below is from one of my healthy looking dahlias.


Now here is photo of one of my dahlias with deformed new growth leaves. Does anyone know what is wrong with this dahlia? If so please let me know. I would really appreciate any advice. The healthy dahlias are putting on buds and I can't wait to see the blooms. I'll be posting some as soon as they open.
