Strength Modifier not showing up on weapon

[EdgarRoniFigaro]

No matter what I do I cannot get the strength modifier to show damage on my weapon. Everyone I talk to in game says they have one and when I played years ago I had one. The only thing I see in the details is my Damage, Critical, and BAB. And it does not matter if I remove strength equipment and my modifier lowers the damage of the weapon never changes.

Can someone PLEASE offer me some advice on what I can do to fix this? I have tried to read through the forums and found nothing on it. I would greatly appreciate any help. Thanks.
