My Neptune dos, is missing the gallon amount i selected for it, in inital setuo which is 18927 = 5G it missed it by roughlt 800 ml. Same thing for the remove, on both heads any idea why?
Are you sure you are seeing the very last dose of the day. Bring up the calendar for Feb. 17th and see if there is a final dose of 800 ml.
On mine, the very last dose of the day has a different number to bring the total to the requested amount.
