Tag missing in vCard

[cerri]

Hi to all,
I don't where to open this thread, so I open here in installation.

I've a 8.0.4 installed and users using their iPhone / iPad with contacts merge.
The users now see duplicated address field: from my research, I found this little difference:
iCloud:

BEGIN:VCARD

VERSION:3.0

PRODID:-//Apple Inc.//iOS 7.0//EN

N:Name;Surname;;;

FN:Name Surname

ORG:Company;

item1.EMAIL;type=INTERNET;type=pref:email@address.com

TEL;type=WORK;type=VOICE;type=pref:+39 (000) 00 00 000

TEL;type=WORK;type=FAX:+39 (000) 00 00 000

TEL;type=CELL;type=VOICE:+39 (000) 00 00 000

item2.ADR;type=WORK;type=pref:;;Street Name, 61;City;XX;00000;Italy

item2.X-ABADR:it

END:VCARD
Zimbra:

BEGIN:VCARD

VERSION:3.0

PRODID:-//Apple Inc.//iOS 7.0//EN

N:Name;Surname;;;

FN:Name Surname

ORG:Company;

item1.EMAIL;type=INTERNET;type=pref:email@address.com

TEL;type=WORK;type=VOICE;type=pref:+39 (000) 00 00 000

TEL;type=WORK;type=FAX:+39 (000) 00 00 000

TEL;type=CELL;type=VOICE:+39 (000) 00 00 000

item2.ADR;type=WORK;type=pref:;;Street Name, 61;City;XX;00000;Italy

END:VCARD
The prodid is the same because I did the export from an iPad mini (where accounts are matched fine except for the Address where the user shows two addresses even they are the same).

My conclusion is that vCard from Zimbra is missing the item2.X-ABADR:it tag: is it right?
And if it is so, is it possible to add it?

Anyone?

Is it possible to add the tag?
