Runes in Staves and Wands

I've lost track of where GGG is at with this with all the updates and upcoming changes.

I've socketed runes into a staff 2x Iron to be precise for the 20% increased spell damage. Normally on Melee weapons you can see what the runes do but it is not showing up on my staff.

Is this normal, or just not quite fully implemented yet or a bug?
