No that is not checked under the water tab. All additions show under a "Water Prep" step, which is the second main heading. The first heading is "Prepare for Brewing".
Are you using a profile in the BS3 database or manually entering? If you are manually entering from EZ water or other program, you will need to manually select which step to use which addition. using the profiles that are loaded in, it should separate them. Here is the brew steps for my brew tomorrow and it splits the additions up. Not sure what setting you are missing - sorry.
