Tracking my children on their Apple Watches not working

Recently, my 3 kids got apple watches which my hubby and I use to track them. All was going great, but I was having unrelated issues with two of my kids' iPad devices, so I removed these two kids from Screen Time, then added them back. This fixed their iPad issues, but now I can't seem to track them on their watches. Instead, it looks like they only trackable device is their iPads, and I can't seem to force my iphone to figure out that I need to track them on their WATCHES. (The child whose Screen Time was not touched is still trackable on her Apple watch.) Can anyone help?
