Why does the calculator want me to add more acid to the mash then I select All grain vs. BIAB given the same amount of mashing water?

No HCO3 in Briess? I’ve heard it’s quite high

Anyone knows the mineral content of Briess LME and DME Since I often use some extract in my high gravity beer it would be useful to know Also whats the pH and would it affect the pH of my wort when I add it after mashing (I guess not)?
