[GRO] Milestones (Infant/Toddler/Children) disappear on reload

I have the same problem as well. I’m playing in a single save file with one household. With my first child, the baby milestones were there at first. Then, when they became a toddler and later a child, all of the toddler milestones disappeared after aging up to a child. With my second child, it now even says that the earlier life phases are not applicable, even though I’ve played with her since she was a baby. Very annoying. I don’t have any CC installed.
