CoursePress Import Issue not resolved with last update

Hi, I brought this issue to your attention a few weeks ago. When you import a course and check “Replace course if exists”, the units are duplicated. For example a course with 6 units, after import, there is only one course (not duplicated) but there is now 12 units!!!!

In our previous chat, the problem was replicated. After the new update, the problem persists.
