Contacts no longer shows the alphabetic breakdown
This happened after deleting one contact when using High Sierra. All groups except 1 no longer show the ABC breakdown, nor is it shown if "All" are listed.
I have migrated to a new Mac using Mojave 10.14.5 and the problem is still there.
I use iCloud and its all OK on ipad & iPhone.
I have tried looking at Contacts settings bu cannot find a solution there.
A little bit annoying any thoughts anybody please?
