When a client is loaded, ParaPlan searches for all the appointments that match the Client ID of the client being loaded.
Every now and then we get a situation where an appointment partially saves and it ends up with a Client ID of 0.
When a new client is created, it has an ID of 0 until it is saved.
Thus when a new client is created, it shows that phantom appointment.
These appointments get cleared out automatically every time there is an update with a database update.
