'+' Option at end of the lessons page don't function similar to the 'Add Content'

Scenario 1:
1. Login as Instructor, Select one of course test site, click on Lessons
2. Before starting make sure we have some files (or contents links) already in the page
3. Click on ' + ' at the bottom which says "add new item at bottom of this column" -> Click on 'Add Content Links'
4. Click on 'select existing files from Resources'
5. Select more than one files from resources. -> Click on 'Continue'
Problem:
The Uploaded files are not in order - some of the files are listed before the existing files on the page and some after the existing files on the page.
(Note: The 'Add Content+' -> 'Embed content on page' also fails)
