Proficiency Bonus not calculating for Warlock spells
I have a Wizard character (level one) with a proficiency of +2 and Charisma +6 but when casting and or attacking using Eldritch blast it is not calcuting the attack with the +2 proficiency. Accoridng to the PowerGroup-Spells attack is Base+Proficiency+(Blank) however when the roll its only adding their +6 Charisma but not inlcuding their +2 proficiency. Is there a way to fix the issue or is there a reason their proficiency isnt included during their attack roll?
