Motorola Droid X :: Can No Longer Edit Contact Groups Since Last System Update

Ever since the last system update, the Contact Groups I created have an icon with a padlock next to them and I have no capacity to edit their content.

I can create new Groups (I assume, because there's a button that says I can), but can't change existing ones. I've tried going to the individual contacts to see if the group designation reside there now, etc. I'm wondering if this is tied to Verizon's Backup Assistant, somehow, though my groups don't appear on the web interface for that service at all.
