Problem with local folder

[texsit]

Hi All,
I'm using Zimbra Desktop 2.0 on Windows 7 64 Bit. I think I have a problem with local folder for calendar and contact.
I'm the only administrator of my notebook.

If I try to send an appointment of my local calendar, I can't write the mail address of the recipient. The box where I should put mail address appear in a grey color and it's not modificable (see picture 1).

Anther problem is with my local contacts. If I write a new e-mail, I push the button A: (or CC: or CCN because i like to see all my contact list.
I noticed that I can see only the contacs that are sync from google account and I can't see the local contact folder (see picture_2 and picture_3).

Are these a new bug?
How can I solve this problem?

Thank you in advace.
