Validity period issue

We are able to load the course level learning records along with all the dates but the validity period rules are not getting set what it is set in application

We are trying to do a data load of learners records that include validity periods on the course.

Courses have been created with validity periods. When we do a learning assignment for the learning history in the system the validity period settings default where as when as when we review a learning record that's been loaded for the same course it's appearing as 'Never'.

How can we get the validity period to work when loading learning records
