Blind enemy should not affect ranged attack.

I notice an adjacent enemy I have blinded still causes disadvantage due to "Ranged attack with enemy nearby".  

Aiming a ranged attack is more difficult when a foe is next to you. When you make a ranged attack with a weapon, a spell, or some other means, you have disadvantage on the attack roll if you are within 5 feet of a hostile creature who can see you and who isn't incapacitated.
