I dont know how i managed but some contacts in my people app have same numbers 4 times. (tranfered directly from N9) If i try to delete them separately they allways come back.

Once looked what numbers my SIM had but there was only operator help numbers.

I have developermode on and running Whatsapp.

EDIT:

Guilty part is my old N9 not Jolla device. Afther i removed my SIM it has made some trics like it sometimes does.
