Need Help With a Dialog Bug

[aussj5link]

Before you look, I know it's messy, but it works thus far for what I need. This is part of my profession system which can be activated when the first recipe is acquired through either a quest or by finding/buying the recipe book. If you have already obtained the first recipe for say, First-Aid, then any recipe books will be unuseable and will give a message saying that you already have that recipe. I thought I had that all figured out but recently while testing out some spellbooks I came across a recipe book which I already had the recipe for, I decide to click it and test it while I was doing other things and it used the book and added another First Aid button and Wool Bandages button to the dialog menus. Below are the triggers I have used for it all.

This is the quest which can give you the recipe:

• Bandages Complete
  • Events
    • Player - Player 1 (Red) Selects a unit
  • Conditions
    • TuftsOfWool Equal to 5
    • (Triggering unit) Equal to Brom |cffffcc002|r 0006 <gen>
    • ((Sorceress is in (Units in (Region centered at (Position of Brom |cffffcc002|r 0006 <gen>) with size (350.00, 350.00)))) Equal to True) or ((Wizard is in (Units in (Region centered at (Position of Brom |cffffcc002|r 0006 <gen>) with size (350.00, 350.00)))) Equal to True)
  • Actions

    • Set BandageKnown[1] = True
    • Trigger - Turn on Wool Drops <gen>
    • Trigger - Turn on BuckleyIntro Start <gen>
    • Special Effect - Create a special effect attached to the overhead of Brom |cffffcc002|r 0006 <gen> using Abilities\Spells\Other\TalkToMe\TalkToMe.mdl
    • Set QuestAvailable[4] = (Last created special effect)
    • Wait 4.00 seconds
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions

Like I said, it's a mess! But it does everything I need it to, or at least it did when I first tested it. I don't know what has changed since then but if anyone can spot the problem I would be very grateful.
