When choosing to import material from another course, a maximum of 10 courses are presented, with no way to seek to additional courses. Looking into the code, it seems that some option for pagination should be presented, but it is not displayed on this course. This bug was identified on the latest download available from the Moodle.org website as of today. I've attached a screenshot showing how a user has more than 10 courses but 10 and only 10 are displayed.
