Why contacts twice?

I have been on my huawei p9lite what's app since yesterday and since then all contacts are duplicated. If I delete one, however, they are both gone somehow. What stupid mistake do I make?

That's because your contacts who also have What's app again and again stored separately.

And how do I get this individually again?

Ma

Unfortunately this is not possible.

That's the same with me, is quite normal, because WhatsApp saves the contacts again… So you have to live well now
