In attempting to remove excess liquid from a reservoir, I am unable to achieve the correct value in the reservoir. There is 58kg of liquid I wish to remove to get an exact quantity of 2500kg in a reservoir, which will be utilized as the high threshold in automation. Regardless of whether the output pipe is primed or not (in which case there is 68kg to remove), I am always left with the incorrect amount shown in the reservoir. It seems the reservoir is bugged, as it will not replace the last <10kg packet taken by the meter valve. As seen here, there is a 2kg packet in the reservoir's output pipe as it displays 2508kg volume and persists upon save/load. This histeresis breaks any finely tuned automation for volumes that are not evenly divisible by 10.
Fill a reservoir with an indiscriminate volume that is not divisible by 10.
Attach a meter valve to the reservoir's output pipe.
Using the meter valve, remove a volume that leaves some amount divisible by 10.
The reservoir's displayed volume does not reflect the correct, desired volume, and the output pipe will contain a packet <10kg.
