Why some Google contacts are not showing? Note 4

[AC Question]

After the android 5.1.1 upgrade of my Galaxy Note 4 some google contacts doesn't show up in phone contacts app. This concerns most of contacts but not all of them. I checked that these contacts are present online in the Google contacts. Anniversaries are also present in the calendar. Also, I selected all the google contacts categories to be shown in the phone contacts app. It was working fine before the update to 5.1.1.
