Titania Beguiling Lantern augment not working

[Polarwaved 7]

At first i thought that it just seemed like it didn't do much, but i decided to test it out in the simulacrum. It doesn't work. I was using the Stropha against corrupted heavy gunners (lvl 110), the damage did not rise at all when using the augment. The augment is supposed to make enemies affected by Lantern take 100% more melee damage, and it even scales with power strength, for me it was a total of 229% more damage. Yet it didn't do anything. Does the mod work way differently from what i'd imagine or is it broken? While on the topic of melee and Titania, her exalted sword Diwata needs a buff, it just isn't up to par with her exalted pistols or normal melee at all.
