Lactose (milk sugar) increasing ABV%

[FBorrego]

Hi BF Forum,

Can you guys check why "Fermentable - Lactose (milk sugar)" is increasing ABV% ?

While increasing OG/FG is normal, lactose is un-fermentable and cannot be considered in ABV% formula.

Thanks! Cheers!

I just tried it- for a 10.5 gallon batch, both the OG and FG went up four points, which would be correct. Can you post a screenshot, or a link to your recipe, so I can check it out?

I tested it too and 1 pound did not make the ABV% change

Sorry guys my mistake.
Actually, the ABV% didn't change at all when i just exclude lactose...
