Has anyone noticed that the 2nd Actor Value of a Dual Value Modifier Magic Effect has no effect?

Maybe I'm doing it wrong. Here's my setup:

Magic Effect properties:
Name: MyME
Archetype: Dual Value Modifier
Casting: Constant Effect and Self
Actor Values: Stamina and Magicka

Spell properties:
Name: MyAbility
Type: Ability
1 x Magic Effect: MyME with Magnitude 10

Quest properties:
1 x Alias: Player with Alias Spell: MyAbility

In the game,
I get the Ability in my Magic Effects list.
But when I go to my Skills screen, my Stamina is green/buffed at 110 but my Magicka is white/normal at 100.

Is "Dual Value Modifier" bugged?

It's working fine. Take a look at destruction spell/magic effects - ice and shock.

Thanks! I'll check out how that is setup.

"2nd AV Weight" defaults to 0. I had to change it to 1 so that the 2nd AV is equally affected as the 1st.
Thanks!
