Groups show double on iPhone contacts

Further to my previous post and to be more accurate.

I have now 2608 contacts showing on iCloud, on my iPad and on the Mac.

On the iPhone I have 2659 and, as previously explained, groups show double.

Kind of weird behavior, isn't it?

I did on the iPhone. All other devices are fine.

I would try logging out of ALL devices and see what happens then....

Thank you but I am reluctant to do so.

For the sake of debugging, why ALL devices and not just one other?

And what about the contacts, should I keep them on the device/s or erase them?

Erasing them would mean for sure loosing the 51 extra contacts I now have on the iPhone and don't sync, don't you think so?

Last time I tried such an action, things probably got worse with the duplication of Groups on the iPhone hence, I would rather not poke randomly into the system without any indication that such action can definitely fix my issue.

I wonder if a complete “reset“ of cloud contacts is possible similarly to what was available a few years ago with the Photostream.

In that process (data reset) the integrity of data was still preserved whereas logging out all devices doesn't really do much to cloud settings, does it not?

OK guys, I found a solution for this without nuking completely everything, maybe somebody is interested in how.

• Turned off iCloud syncing of contacts on the iPhone and the Macbook.
• Made a wired syncing and copied all contacts into the Macbook Pro.
• Edited contacts by removing all duplicates of both, contacts and groups.
• Resumed iCloud syncing on the Mac.
• Resumed iCloud syncing on the iPhone selecting to replace all contacts on iPhone when asked.
• Edited all contacts again on Powerbook.

Syncing correctly has now resumed among all devices and contacts appear to be the same number on all of them.

As a side effect also automatic backups on the iPhone have restarted regularly.
