Lost half my spark damage when i equip a 2nd staff

I noticed my spark damage was cut by 60% when i added a sigal of power on my 2nd weapon set.

I noticed its not taking into account my + to skills at all for my staff or any damage mods on it i swap between a white blank staff to my usual one and the dps isnt changing.It does add the skills from amulet tho. If u need video support lemme know but this essentially bricked my sorc.

I unequipped all gems and gear and put them back on to try to fix it nothing help??
