Child properties disappeared from parent animation

I’m not sure what I did. I didn’t update anything, but all the sudden Unity changed the way I can animate child properties. Before I was able to animate child objects in a parent objects animation by selecting the “Add Properties” button under the “Animation” Tab after selecting the parent object with the animator in the project hierarchy. From there I was able to change those properties on the animation tab’s timeline.

However something changed and I don’t know how to change it back. I don’t know if I accidently changed a setting or pressed a hot key, but now when I click on the “Add Properties” button then select a property from a child object in the dropdown, nothing happens. Instead, now I’m able to animate the individual child objects on their own timeline, but not along with the the objects in the main parent object’s timeline like I could before.

The other thing I noticed is that if I find and select the animation under the “Projects” tab, I can see all the child properties that I had set up before, but when I select the game object with the animation in the project hierarchy, those child properties are not visible under the parent’s animated properties like they used to be. I hope I explained that right, and there is just some stupid little setting I accidently made. I’ve looked everywhere online for the answer.

Edit to add. It’s doing this to all animations on all scenes. And like I said before. One moment it was working as expected, and the next minute it wasn’t. I’ve restarted Unity and reset to default layout.
