Bukkit

What steps will reproduce the problem?
1.Place a horse for sell - the name of the horse changes to Name $amount
2.Tame a new Horse
3.$Amount is removed from all horses for sell. They are still for sale by clicking on the horse, it gives you the options to click again to buy, but the amount is not there.

Also, If i click Horse1 once, it will ask to click again to confirm, then I click Horse2 to check price, it will count that has my 2nd click-to-buy and automatically buy the second horse on the first Horse2 Click.
