I may have found a bug in Wazapp contact sync. I dont know if it was reported before.

I have 2 contacts with last 8 digits of phone number same . For eg:

PersonA : +8111(22345678)
PersonB : +8167(22345678)

Now, Person A has WhatsApp and PersonB does not have Whatsapp account.
Still, PersonB shows up in my Wazapp contacts, with PersonA's phone number. This is wrong.

Hope the devs get a chance to fix this.

Thanks for the great work by all the devs.
