Not sure if bug or intentional, but the Exp cost for the Lure enchantments seem off.

Currently:
Lure 1 - 100 Exp
Lure 3 - 1500 Exp

By the upgrade process on an anvil, to get a Lure 3 from Lure 1 rods, you would need four rods with Lure 1, which at base value would be 400 Exp, not even 1/3 the amount for a straight Lure 3 enchantment (not including upgrade costs in the anvil).

Anyway, the Lure 1 cost should be between 300-350 if we are staying with the trend of other enchantments that have lower enchantment options
