I have a recipe that is a 2.5 gallon BIAB with 2 gallons of water I batch sparge with. In other words, I do a 2.5 gal mash, then run up to (but usually less than) 2 gallons of water through the bag in a colander to reach my pre-boil volume. I treat 4.5 gallons of water at once. I do the same thing for 5 gallon batches, and the linked water calculator works perfectly, but for some reason, with the 2.5 + 2 = 4.5 gallon setup in the water calc, the mash ph is screwed up and the sparge water is zeroed out, treating it as if my salts are all added to the smaller mash volume alone.
The water calc is fine until I EDIT the recipe. I don't even have to save the recipe, I just load it in the recipe editor, and then the water calc (can be on a totally different page) is updated to 0 sparge volume if I refresh the water calc, even without saving the recipe or water calc. I've tried creating recipes from scratch, everything, it just seems to refuse to work with my 2.5 + 2 = 4.5 gallon water setup. When I do 5 + 2 = 7 for larger batches, it works and the sparge water stays and the mash ph agrees between the water calc and recipe editor.
