Equipment bonus issue?

[Khayin]

First, I want to say thanks for all the hard work everyone has put into this program! It was like Christmas came early when I found the WoD data package available this morning. I'm looking forward to employing it in my upcoming game!

Now, on to business -- I can't make sense of the calculations for equipment bonuses relating to combat. Attribute + Skill + Equipment is the equation I use, but the sum always seems to be one die lower than I would have thought to be correct. My test character, for example has a Dexterity of 3, Firearms 2 and wields a Light Pistol with a damage rating of 2. Putting that all together, I would have expected a dice pool of 7, but it is registering as 6 in all areas of the program. So far, this has held true for every weapon.

So, I guess the question is: am I simply not aware of a rule that affects this total, is there some factor affecting the pool that I am not seeing, or is this a bug?
