You are indeed misunderstanding the instructions, though this one is rather easy to misinterpret if you're not a native speaker. Options 1-9 are combat specific. They are all linked to one another and no others. The naming is similar to the options at the very bottom, which allow you to do things in the editor. To summarise, options 1-9 are combat specific, the rest are everywhere else specific, except the XP multiplier. Haven't been able to crash the game with that one yet.
You also have to be OUT of combat to edit weapons, as you need to be able to access your inventory to do so.
