Covering lessons in the Sixth-Form [SC]

StaffCover:  Two questions on covering lessons in the Sixth-Form:

 1    In the Sixth-Form, we cover L6th but not U6th:
Q. In StaffCover, we want to cover L6 (Year 12) but not U6 (Year 13) - is this possible ?

A. Yes - Go to "Customize -> Cover Options" and select 'Your Sixth form is Year 13 and above'.
Then make sure you have selected "Cover your 'Sixth Form'" as 'Never'.
This will ensure that Year 13 are not covered.

 2   We never Cover the Sixth Form:
Q. Despite setting the default to ‘Never cover Sixth Form’, this is being ignored, and Sixth Form lessons are having cover allocated. Am I missing something?

A. Go to "Customize -> Cover Options" and check what years are defined as being your "sixth form" ("Your 'Sixth Form' is:").
