Contact Favorites disappearing

[Jeff Wiederholt]

Contact Favorites disappear every night. Favorites update with new Contacts during the day as I use my phone but in the morning they have disappeared. This has been going on for several weeks and never used to happen. I've had this phone for a couple of years I've changed nothing in my Contact software that I can think of.

Moto X Pure Edition running Android 7.0

Any ideas?

Thanks,

Jeff
