Could you post your recipe with weights for us as well as your KOH purity? That will help us troubleshoot and let you know how to proceed.
Since you already know you have a 35% lye excess, you will probably be recommended to add the amount of OO you are missing back into the paste so it will neutralize the lye excess. However, without knowing the exact weights I don't want to recommend that just yet! It could be a math error or something else. It happens!
