Zealot charge does not reatore 100% toughness

With the feats I have I am supposed to get 50% restored toughness on charge and another 50% restored on melee hit. I only get 50% restored toughness so I think zealot is broken.

Which Feat? on first tab at level 5?

it means 50% increased toughness on kill, for example lets say 1 poxwalker gives you 5 Toughness, with this Feat you will get 7.5 Toughness per poxwalker
