Hello,
Here is the UX problem :
When an user want to add a contact :
- he click on “+” button on the contacts app.
- he see the focus on “Name” field.
- he start typing and the name field is filling up.
- he enters the others fields like email, address, etc
- he save the contact
-> the contact is created without any name because the change he made in “Name” field was not validated through the name-popup :

I suggest to show the name-popup when the window of new contact appear :
I posted a Merge Request about that here on October 22 : https://github.com/EGroupware/egroupware/pull/206
Regards,
John
