You can edit the profile within the recipe by clicking on the check mark icon right next to the mash profile on the mash tab. This will open up the profile for you to edit within the recipe. It will not save the profile anywhere else, so if you want to make it permanent for that particular profile, you will need to save it by clicking the disk icon next to the check mark icon. This will create a copy of the profile in your master listing of mash profiles, so you will need to go back through and remove the old profile.
BeerSmith treats each recipe as an individual archive. If you edit a profile outside of a recipe, you need to update the profile within the recipe by clicking on the mash profile and re-selecting the update version. I keep track by noting the date of the changes in the profile name, such as "01a Single infusion, BIAB, 148F, Full Volume 170711".
Likewise, if you edit a profile within a recipe, it will not affect that same titled profile in any other recipe. This allows the user to archive a brewed recipe with brew day data saved and not have the targets updated by a change in the profiles at a later date.
I have attached your recipe with the profile changes made within the recipe.
