Weapon damage bug

[xxchronic2006xx]

Hello,

 

First let me say that my skyrim is patched v 1.310. I actually regret updating because since then I've noticed more problem and crashing... go figure. Anyways, sometimes I will look at my weapon in my inventory and next to the damage will be green text like (+15). When I reequip my weapon its fine and it goes away, but why does this happen? I don't have any disease and I didn't pick up or use some sort of stat enhancing bonus.

 

Thanks for the help
