Endless grill meat-fetching loop

See the attached save. Soon after loading (maybe a minute or less), a dupe (usually Camille) goes to the leftmost refrigerator and picks up meat to deliver to the electric grill (which currently has 1999g of meat). It says "Picked up: 999.5mg meat", and the fridge contents go down by about 1g. But her "Carried items" is empty, and she travels to the grill then delivers nothing, and the grill still only has 1999g. She and/or other dupes repeat this same process many times and never manage to deliver anything.

I assume it is some kind of rounding issue with small amounts of meat.

Because the grill is trying to produce a barbeque, but doesn't have enough meat, it gets stuck on barbeque and never moves on to the next order. I'm not certain but I think the problem has been going on for many cycles by this point, and my dupes are sad since they haven't had any grilled food for ages.

If I "empty storage" on the grill then the problem seems to go away - it gets correctly refilled with 2000g of meat and starts producing food again.
