So when I check the report of a Totara instance,

how can I figure where a particular field is coming from ?

Say for example, I have this site running Totara 13

In a course completion report, there is this column field that can be added called sub-sector-category and it is visible under the parent - 'Organisation'.

However when i try to recreate this report, i am unable to find such a field or custom field.

i checked course custom fields and couldn't find the same.

any idea how to fix this ?
