Cannot see phone numbers of my gmail account

I have just bought an MX5 and immediately updated to and then factory resetted.
All things works but one, the most important.
I connected it to my gmail account.
I sync the contacts but when I go to the dialer I see all names but without phone numbers so I cannot call anyone and when they call me I do not see the name but the phone numbers.
Contacts in sim work.

What can I do?
Please help me!

PS: I have already installed several apps so please do not tell me to reset the phone again.

@Mario-Giammarco Update: I go in the google contacts on web. There I use the remove duplicates to clean some garbage. Now the contacts updated are also in the phone with phone numbers. But only them!

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
