Export/Import

I have Windows Live Mail 2012 and Windows 10.  Windows Live Mail has a feature import and export.  Sometimes export works and sometimes it does not.  You must keep doing it over and over to finally get all your folders to export.  OK, I can deal with that problem.  But the import is a whole other story.  You can import but your folders, like mine, are under my default email and that is exactly how they export.  But when  you import those exact same folders they don't go under your default mail like they were exported.  They go to the bottom of the list under about 8 other emails account under the heading of "Imported Folders"  How do you get those to import in the same structure they were exported as.
