Motorola Droid : New Contacts Created On Phone Disappear / Need Back

I've had this happen three or four times now...two types of occurrences:

1. Edit an existing contact...when I select "Done" the screen says "Saving" and then returns to the contact list - and the contact I edited is gone.

2. Create a new contact - enter name, address, phone, select Done, "Saving" message appears, return to contact list, and the contact is not in the list.

Looked under all variants of the name (first, last, etc.) and it's just not there.

I'm creating the contacts on my primary account.

I'm on 2.01, no rooting, using the built-in contact manager.
