I am trying to configure my water chemistry and there is not update button as before., i pick my water profile and then target and go to add salts and water chemistry does not change - is this broken?

Ok guys the opinions vary on how long pilsner malt needs to be boiled (either 60 or 90 or something i between) Brulosophy did a test and discovered there is no difference between 60 and 90 min boil. Have you guys had any experience with 60 min boils or do most still do a 90 min boil?
