126k is the dmg you are looking for.
however you seem to have items on your charater that deal % Holy Dmg (like on Bracers, Amulet, ...check your items for that) which is added to your sheet dmg, but only when you are using Holy Skills to do dmg.
In your case you deal 158k with holy skills, and 126k with skills of any other element.
In case you didnt know. Hover over your skills to see which elemental dmg it does. Usually you can change the rune of that skill to get it to deal another type of dmg (but also get another effect of course, as you might have noticed )
