Segment filters only work when first saved after upgrade to version 3.0.1

I have a number of saved segments that I use to filter my visitor log by client. After the upgrade my segment filters stopped returning results. I recreated a few of them from scratch and they worked the first time I saved/applied them. The next day I opened the filters however, they didn’t return results again. Recreating them a second time caused them to filter properly again. Any ideas on what my be causing this?
