Unhappy Nexus 5 merge / join contacts after upgrade to 4.4.3

Hi,
When I started using my LG nexus 5 phone and added my google, hotmail users the phone automatically merged same contact names.
I noticed in the last week or so that all my contacts have been seperated - I think it's after upgrading to 4.4.3

Can anyone help here?
Thanks
Yossi
