Visual Bug- Windspeaker's Blessing heal/shield buff description

In the masteries page and the patch notes, it says :

FIGHTING SPIRIT Your shields and heals are 10% stronger POWER OF FRIENDSHIP Your shields and heals on allies other than yourself grant them 15% increased armor and magic resist for 3 seconds

However, in game, when you mouse over it, in the tab, says that your shields and heals are 10% stronger (excluding on yourself).

I'm not sure which is actually true (whether heal/shields are 10% more effective on self), but one of these is a bug.

(Also Excluding is spelled Exluding)
