Thanks, Medarius!
Yooper - below are screenshots from two test recipes I created this morning. I am on a Windows computer and am using Google Chrome.
Here is recipe #1 with acid malt in the grain bill. It has been saved and no water calc has been created yet. The estimated ph is listed as 5.31:
I created a new water calc for recipe #1 and there is 4 oz. of acid malt automatically included in the Acid Additions section, in addition to the acid malt in the grain bill:
I have deleted the acid malt from the Acid Additions section and the estimated ph is now 5.58. I saved the water calc:
I then updated the recipe and the estimated ph in the recipe is listed at 5.31 rather than 5.58:
I saved the recipe, closed the browser window, came back, re-opened the recipe and the ph still said 5.31. So I went in to edit the water calc and the extra acid malt in the Acid Additions section was there again:
I then created recipe #2, exactly the same but with no acid malt in the grain bill. The estimated ph is 5.85 before creating a water calc:
I created a new water calc, there was no errant acid malt in the Acid Additions section, and the estimated ph matched what the recipe stated before the water calc was created:
I added the same amount of acid malt to only the Acid Additions section and the new estimated ph was 5.57, right in line with recipe #1 (minus the errant acid malt that showed up in the water calc):
I saved the water calc and updated the recipe. The ph in the recipe matched the water calc this time:
So to me, as I mentioned in an earlier post, the issue seems to be that when acid malt is added to the grain bill in a recipe it shows up twice in the water calc, once in the grain bill and once in Acid Additions. Deleting this extra acid malt from the water calc doesn't seem to make it go away once the calc is saved and the recipe is updated.
The obvious work around is not to add acid malt to the grain bill and just add it to the water calc. That's not a huge deal but the acid malt won't show up in the shopping list then so you also have to remember it or add it manually.
