How to show only gmail's contacts in the Contacts app? I have recently reinstalled Android due to some problems with the SD Card.
I decided to keep all my contacts only in Gmail, as a centralized solution to avoid problems in the future. I do not want other SIM or phone contacts to show in the contacts list anymore.
However if I try to uncheck both the SIM and phone contacts and I do check all possible google contacts groups and the option for showing only contacts with a phone number1, no contact is shown at all.
Note: If I show also the phone contacts them the google contacts are shown (and thus I have some duplicates), but removing the phone contacts removes the google contacts too.
How can I prevent this?
The phone is a B63M.
Edit: since people keep asking the same information:
The contacts are perfectly synched and all under the My contacts group. It's not a synchronisation problem. I'm asking why I must select the show phone contacts in order to see any contact at all (from whichever source you like. Even SIM. I cannot show only the SIM contacts without the show phone contacts enabled.)

1 Having or not this option active doesn't change anything. Even if it is not active no contact is shown.

To make things clearer, here are some screenshots of the situation:
Here I have set only the phone contacts (Contatti del telefono in Italian), without google contacts:

Here I have added the google contacts in the options and they are shown (see red rectangles. Note the number of contacts at the top going from 116 to 156):

Now, I'd expect that removing the phone contacts I should see only the google contacts (in this case those that above have red rectangles and the other not shown), but this is what I get:

On the right it just says that there are no contacts to show and that I can add new contacts or import/export from other sources.
What should I do such that this last set of options does show the google contacts?
Go to Contacts &gt; [Sitting Button] &gt; More &gt; Accounts.

Be sure the following are checked:


Background data.
Auto-sync.
