Is this your recipe or one that you received from someone else? I am guessing that if it is not your own recipe, that it comes from BeerSmith 2 and when imported into BeerSmith 3, the instructions for the hop additions are set to the default (specifically the addition 3 days before bottling). This nomenclature is new in BeerSmith 3 so it does cause some confusion with imported recipes.
I would look at the whole recipe and adjust the addition time to make sense with the days in contact based upon the original intention of the recipe.
