IMS Enterprise plugin not respecting default course settings when creating courses

We have used the IMS Enterprise plugin to create courses and update enrollments on Moodle 2.9, 3.2, 3.4, and 3.6. On Moodle 3.4 and 3.6 we have noticed that courses created by the IMS Enterprise import file are not respecting default course settings, particularly the default number of sections a course should have. Our default course settings specify the weekly format with 10 sections. When we first started using the plugin on 2.9, it created courses matching all the parameters in the default course settings. Courses created by the IMS Enterprise plugin on Moodle 3.4 and 3.6 have a weekly format and 0 sections.

This might be related to behavior reported when attempting to upload courses: https://tracker.moodle.org/browse/MDL-63268 

To reproduce the issue:

1. Confirm default course settings specify a number of sections higher than 0
2. Upload an XML file with new course data
3. Settings for IMS Enterprise should be set to create new courses if they do not already exist
4. Perform an import of the IMS Enterprise file (or wait for the cron to do it)
5. View a course created by the IMS Enterprise file
   1. It SHOULD have the number of sections specified by the default course settings
   2. It ACTUALLY has 0 sections
