Convalescence broken. Say "Item can not be used: -Not usable with the current weapon set setting"

I was using the spell 2 second ago and try another aura for calculation purpose. Now, I can't activate convalescence anymore. Have enough intel to used it on both weapon set, have enough spirit to use it(unbuff all other reservation). Still can't reactivate it and I dont use any minion, playing a rampage titan.
