In wplms batches 1.6 version we have added a new setting in the course settings (front end), which hides the expired batches from the course page.
This setting is usefull for course instructors if they offer many batches for the same course, for example:
There are 12 batches in a course from January to December, then obviously you do not wan the students to see the January, February and March batch in the April month, because they won’t be able to enrol in that batch now.
