Icon boxes show 0 events. yet there are events

Both my cameras now show 0 events in the icon boxes. Yet when you click on the box there are events recorded. Plus 1 camera has a menu icon with a clock red dot. I did reboot both cameras.No change
Both issues were not popping up before. Have had the cameras for a 18 months now and worked flawlessly except corrupt sd cards, which I replaced a few months ago
