Awakened Generosity lvl 10 and +2 Aura Gems

When I put a level 6 Awakened Generosity in a +2 Aura, +1 Strength helmet, and use the Runegraft of Gemcraft for another +1, I end up with a level 10 Awakened Generosity. The gem (and the Wiki) says it is now giving +2 to linked aura skills, but it is only giving +1.

This wouldn't be that big of a deal if I hadn't been working towards this upgrade for the last week and spent over 100 Div to set up it (2 3 passive voices, helmet, gem, etc, most of my money).

If you would be so kind as to review this and either correct the gem description so others don't have to lose so much time and money or ensure the extra level is actually applying I would truly appreciate it.
