Anvil "Too expensive"

When repairing weapons on anvil in Survival mode, you'll get the message "to expensive".
By switching to creative mode you will see the needed xp-Levels.

The Problem is that the Message "to expensive" will appear in survival mode, even if you have enough xp.

(Example in screenshots)

Used sword:
Sharpnes IV
Knockback II
Fire Aspect II
Looting III

others = same problem
