Changes of mobile/work phone stored in Outlook app on mobile

Hey,

 

I synchronized contacts from AAD on my mobile device via Outlook app. Went well.

Then I changed mobile phone (reproduced on work phone) and after synchronization Outlook stores 2 values of each (when I repeated change with other values, still only 2 of each were there).

Another problem is that Outlook in profile short view displays randomly one or another value. In AAD however everything looks properly.

 

Any ideas?

 

Regards,
