S8+ icon notification badge not displaying numbers

[JeffAZ]

All of a sudden my s8+ which as been working fine started showing solid white notification badges on icons. The unread numbers are gone and all that is displayed is a solid white round circle. If I open the app to clear the notification, the blank circle disappears until another message comes in, but then all I see again is a solid white round circle on the icon without data. I have tried to reboot but no change.
