Solved Items still spawn

[SuperTommyDog]

So i am trying to make a generator for a farming server and when you destroy the generator it keeps on spawning the items. It has 0 errors and i have no idea why it still spawns or how to make it so it doesn't. Please help.

on join:
    set {genlimit::%player%} to 20
    set {gens::%player%} to 0

on place:
    if event-block is a hay_block:
        if name of player's tool is "&e&lWheat":
            if {gens::%player%} >= {genlimit::%player%}:
                send "&6&lGen &6>> &cYou cannot place over %{genlimit::%player%}% Generators!"
                cancel event
            else:
                add 1 to {gens::%player%}
                set {_loc} to location of event-block
                add 2 to the y-coordinate of {_loc}
                add {_loc} to {wheatgen::*}
                send "&6&lGen &8>> &aYou have succefully placed generator %{gens::%player%}%"

every 7 seconds in world "Plots":
    drop 1 wheat at {wheatgen::*}

on break:
    if event-block is a hay_block:
        set {_deleteloc} to location of event-block
        remove {_deleteloc} from {wheatgen::*}
        remove 1 from {gens::%player%}
        send "&6&LGen &8>> &cYou have destroyed a generator you now have %{gens::%player%}%"

When you set the location of the generator you get the location of the hay bale and then add 2 to it's y coordinate but then you forget to add 2 to it's y coordinate again when you remove it.
