Damaged Fishing Rods not able to be enchanted

Damaged fishingrods when attempting to enchant are given the basic layout for enchantent but when one is chosen nothing occurs, i tried it with a undamaged one and it was able to be enchanted.

UPDATE: Fishingrods when put in a enchant table in the most recent snapshot (14w31a) are given options for enchants now such as unbreaking but ALSO include unlabeled enchants which cannot be applied.
