Create/Delete Appointment buttons not working

[Sammy]

Hi All,
I have a weird situation here. I have Create and Delete Appointment buttons, but they are not enabled. Even if I highlight a number of hours, the "Create" button does not enabled. It's not until after I click on existing appt, that the Create and Delete buttons are enabled.

Here is some stripped down xaml that demonstrates the problem. What am I missing?

Thanks!
