Please let me know if anything else required.

When you create the template only the values which you change get saved to it. So if you want to add the calendar to the template you at need to open the calendar combobox and select the calendar. The same goes with all the other fields too.

rhino, those are not the template settings. You need to check under the [templates] section what gets saved to the template.

Here you go:
