I had this problem a month ago. Power cycling the each vt fixed it. I just checked and post update, I'm not experiencing any problems with child sync or anti sync.
Try a power cycle and see if it fixes it... if not go to settings>troubleshooting >verify settings. It will look for discrepancies and if it finds them it will offer you a choice to resolve them. Click resolve and see if it fixes it. If not use the in app feedback to send them a report.
