Yealink W56 shows only Mobile Number in Handset

[heubi]

Hello
We have a 15.5 Debian install with Yealink W56P and 5 x W56H. I loaded with a csv all contact datas in 3cx an now it shows also in yealink. But it only shows - next to the name information - the mobile numbers field!? How is it possible to show all fields? Configuration fault? Thanks for a short answer.

This is std setup, yealink phones will only show mobile numbers from 3CX contacts
