[Resolved] “Cast on bug” couldn’t be activated with full Spirit (fixed after replacing gem)

Hi Support,

Can’t activate Cast on Elemental Ailment with full Spirit (326/326). Shows “Missing Socketed Skill”. Works only on secondary weapon — can’t use both Elemental Ailment and Cast on Crit on same weapon.

Update (Resolved):
Fixed by replacing the Cast on Elemental Ailment gem. Both skills now work normally.
