Hello JPDeM,
It sounds like many of your contacts are in All Contacts and not under iCloud in the Contacts application on your MacBook. There are a couple of ways you can move the contacts to iCloud.
First, if there are just a few contacts you would like to move, you can drag them from All Contacts to the iCloud section on the left:
Add contacts to a group or folder
Select one or more contacts and drag them to a group or folder.
Organize contacts using groups or folders

Alternatively, you can turn Contacts off and then back on in System Preferences>iCloud. When you turn Contacts back on, you will be prompted to merge your contacts, and this should move items from All Contacts to iCloud:
Turn iCloud Contacts off and back on.
- Quit Contacts (or Address Book on OS X Lion).
- Open System Preferences, and choose iCloud.
- Deselect the checkbox next to Contacts. Click Keep Contacts.
- Close System Preferences, and wait about a minute.
- Open System Preferences, and choose iCloud.
- Reselect the checkbox next to Contacts.
- Close System Preferences.
- Open Contacts (or Address Book) and test to see if the issue has been resolved.
