Weapon Effect not going to both hands.

Hello, I bought the astral weapon effect and in its description it says that both hands should get the effect, but every time I use it only one hand get the effect. I don't know if there is something I should do or is a Bug.

From my understanding, only supporter pack weapon MTX's can be propagated to both weapons in the MTX UI. I also don't see any mention of both hands for "Astral Weapon Effect" description.

If you're sure it should apply to both, include screenshots of where it says both hands and what it looks like in your MTX UI.
