My helmet with +2 to Enchant Weapon shows +2 on the skill page until I try to allocate those points. Once I allocate 1 of those points the other disappears and the skill tree shows no “+2” to the skill.
So it appears that there is some kind of bug that is not correctly reading the extra skill levels from the items prefix.
I will try a different head item to see if it is a bug with a specific type. The head item I am using currently is “Runed Visage”
Update I tried another “Runed Visage” and the same bug occurred. The skill I am using is “Enchant Weapon”.
Thank you
