the +6 level awakened added fire damage supported + Archdemon Crown + Runegraft of Gemcraft

the +6 level awakened added fire damage supported + Archdemon Crown + Runegraft of Gemcraft
the awakened added fire damage supported level = 6 - 2(Archdemon Crown) + 1(Runegraft) = 5
it should add one level to the linked physical skill gem
but now it can not let the physical skill +1 level
it is a bug!!!
