To reset them I unfortunately just did a factory reset. Don't know of any other way, this may not help all over you but you can also export them from google and delete them off your account, should sync and delete them all.
go to settings> applications> manage applications> Contacts storage>clear data.
This will delete all contacts in the address book.
I had some merge issues, duplicates would not merge on phone although I kept merging in gmail contacts, so I turned off sync, deleted all contacts this way and re-synced to google contacts and all is great now!

Thank you so much! This worked!
my hotmail(corporate exchange) contact sync had created many duplicates. Just by unselecting the sync and reselect. It didn't work.
With your tip it worked fine.
Also the contact search of my Android 2.3.4 phone didn't find some contacts that I could find by just scrolling through the list.(yes, I had checked all groups).
Now I can find all my contacts again.
Gingerbread update from Verizon makes this solution not work! Verizon and Moto support have looked at phones (DroidX, Droid 2, Bionic) and they all have the option to delete all contacts disabled.
Level 2 support at Motorola confirms that the "clear data" button under ManageApplications>ContactStorage no longer functions. They say Google did that, perhaps to force you into gmail sync instead of import from text file.
Moto and Verizon suggest doing a factory reset on the phone (which will wipe out all settings and free apps) TO SEE IF THAT DELETES THE CONTACTS. They're not sure it will, and I haven't tried it.
Verizon says they'll swap my DroidX for an HTC Thunderbolt, but while it has the same size screen it's not the same number of pixels...
Or use this app: https://market.android.com/details?id=com.DeleteAllContacts
(which hopefully does not upload a copy of your contacts as it deletes them)
NOTE: Contacts Storage app still shows 63MB of data after deleting all contacts!
Google gets your data and keeps it forever. Deleting contacts manually or
otherwise does NOT remove the contact data from the phone!!
