My Emberfusillade lvl 20 got downgrade to Lvl 18

Before the 0.3.1 Update had a Lvl 20 Emberfusilade Skill but now I noticed that my LvL 19 Fireball skill was missing on the Skill UI due to missing Intelligence. Then I noticed how use my Ember if it's Lvl 20. Turns out it's LvL 18.

As for note I did tinkering with my Skilltree could explain why i had less intelligence for Fireball but not the downgrade of my Emberfusilade
