Delete an unwanted Course from CoursePress Pro

I'm trying to delete a course that I no longer require but I don't seem able to.

I have Administrator access.

From the Course page I click the Checkbox to the left of the course to select the course I want to delete.

From the drop-down list (at the top of the page) I select the option 'Delete' and click Apply.

But the Course remains in the list.

I should be able to delete a Course following these steps? Or is there another method I can use?
