Check the client display in the Sync preferences. The behavior you report sounds like what I would expect if you've inadvertently gotten a duplicate client registered in your database and it isn't getting synced. If you spot a client that hasn't been synced recently, and all of the machines on which you are running OmniFocus are represented with clients that have been synced recently, deleting the old clients should put an end to the problem.
