Easier way is to simply remove Waze from your account lineup.

Yes, it is a bug but I am on at least seventh Android device using Waze and have never come across this issue.

It's pretty quick if you go to the bottom left menu button and tap Delete, then tap each copy. Took maybe 5 minutes. This way you don't have to delete your account.

You don't need to delete them manually one by one.
After deleting waze account from the accounts in the device settings (settings --> accounts --> Waze --> options --> Remove account) and re-syncing Google contacts everything is back to normal and the duplicates disappear.

This was the best solution for me. It worked very well. Thanks very much for the information

I had a problem with something duplicating contacts but couldn't identify the source. I bought the app "Smart merge" which did a good job of cleaning things up, without identifying or solving the cause.

I have the same issue with the duplicating of contacts, and many have been blended together.
I have spent too much time repairing my contact list.
If something is not fixed very soon, I will be un-installing the app and notify everyone I have ever told about the app.
I have enjoyed the app, even though I have never been able to beep anyone. The app has probably saved me from getting a ticket, and for sure saved me many hours of drive time.
MY CONTACTS ARE FAR MORE IMPORTANT THAN ALL OF THAT.

Wake doesn't make it easy to contact them, I don't believe they really care about their users.

Please, I hope there is a solution for this. I can not believe that this hasn't been addresses or fixed - Blows my mine! This App is not new... And this is a known problem for years. This is an UNACCEPTABLE problem. . It is CRAZY all the duplication AND DELETIONS OF CONTACT INFO. WHAT IS THE EASY FIX??

Waze staff does not reliably monitor these forums. You'll need to go through the support page to deal with waze support: https://support.google.com/waze

It may be difficult to get personal attention from actual waze staff. There is a large user base and a small staff. I'm not sure if you can start a dialog with this submission https://support.google.com/waze/answer/6276841

Just out of curiosity, did the submission trigger a response email with a ticket number?

Interesting. Shortly after installing CM11 I noticed I had lots of duplicate contacts, sometimes 4 or 5 per person, but only when I was doing a contact search. If I simply scrolled through my list of contacts I saw no duplicates. They were all empty too except for one which contained all of the contact details. I thought it might be a bug in CM11 but apparently not.

I just followed the suggestion here and deleted my Waze account from settings/accounts and the duplicates no longer appear!

Oddly, when I open Waze (which is still my favorite GPS app) my login information is still there and I still see my points. I would have thought that after deleting my account it would have prompted me to log in again but it did not.

For the record my device is a Droid RAZR HD
