Dial-in duplicate in Outlook when booking a S4B meeting

Hi all!
We have discovered an issue with Dial-in numbers in Outlook when booking a meeting with Skype for Business.
The Dial-in numbers are double in the new release of Outlook 2016 version 16.0.7167.2047, I think that it was the same on the previous version.

We do not get this on O365 Outlook versions and in Outlook 2013
