Steady Hand - wrong text

Inconsistency in several of the texts for Steady Hand

World name: Ragnarok
Character name: Deathloaf Chilisauce

Steps:
1. As an Armorer (might also be for other classes) use Steady Hand while synthesizing
2. Hover over Steady Hand action icon (in the action bar) - shows the text "Improves action success rate by 20% for the next 5 steps."
3. Hover over Steady Hand effect icon (in the current player effects at the top) - "Action success rate is increased by 10%"
4. Which one is it then? 10 or 20 percent?
