Solar Weapon and Soulfire

[Locotomo]

One of my players plays a Solarian.
I created a Solar Weapon for him and used the Forge to combine the Soulfire crystal with it.
The damage calculation doesn't work. It isn't adding the Charisma modifier to the damage.
I even tried to add the charisma bonus to the damage section of the weapon, in the bonus field I added +3, but it still doesn't work.
Any ideas?

I found a part of the problem. The stat entry had 0xStr mod. I had to change it to 1xStr + 3(for Charisma).
