Forerunner 965 has lost icons next to the names in glances and doesn’t highlight the selected option in any menu.

Forerunner 965 has lost icons next to the names in glances today, it also doesn’t highlight any option in any menu. Vibration also seems to feel different. Unsure if this was following an update - running software version 20.26. I’ve factory reset device and restored from backup and still have the same issue. Please help.
