When setting material filter for a critter feeder it auto add some filters.
Eg. I set 'dirt' for hatchling and hatch. When checking the feeder later filters for other hatch types have been added as well. While that may be deliberate why has it also added a filter for vole pups ?
Furthermore the principle of not showing the auto added filters until you close the selection screen and then reopening it is a bit questionable.
