Missing weanling?

I noticed my weanling count is 67 on the Stable Overview, but when I do a general all-weanling search, it only lists 66 weanlings. I suspect it’s from cashing in AMI for a weanling, and the game randomizes a due date. Not sure if it’s pre-counting the weanling or if it should actually be visible.

This issue still persists. Foal might be due in August for all I know, but foal counter still shows 1 more than I actually have and no created foal since cashing in the AMI 3 months ago.
