Server showing wrong Phonenumber label

Hello,

i create an new Contact on my Android Smartphone with 2 phone numbers.
The first Number is labelled as “Hauptnummer” the second as “Zweite Nummer”

At the Server is showing me the Label “Anruf” (for the first Number) and “X-Assistant” for the second phone number.
I don´t know why the Server choose different Label.

My System

Nextcloud 10.0.1
Ubuntu 16.04
Apache2
Nginx as reverse Proxy
PHP 7.0.13 (FPM)

(no logentries)

Android 6.0.1
