Devil's trident and Spellbook builder

[Looke83]

First of all I wan't to say hello to all community. My name is Lukasz and I'm from Poland, so sorry if I will make mistakes in sentence  - I will try to do my best .

As we all know Mage Wars is fantastic game and after buying a core set a week ago I'm now happy owner of all add-ons to this game. And right now I'm constructing Necromancer spellbook and I'm puzzled with Devil's trident. It is death and fire spell so Necromancer should pay normally for putting it into spellbook - and cost of this spell is 1. Unfortunately Spellbook builder is counting it as 3 points - is this correct [I don't think so] or it is error in builder ??

It is a level 1 Fire spell and a level 1 Dark spell. The Necromancer will pay twice the spellpoints for the Fire, so 2, and regular for the Dark, so 1. That makes the total 3.

I figured that later. Anyway thank you for your answer. That's a shame it's a good spell.
