When I am trying to upload a spreadsheet it is not connecting the epics or the tasks, and will add the assignee. I have been trying by using the import examples that Atlassian provided and no real data yet, but I cannot figure out why the link up is not working. Below is the way the screenshot is set up. 
I am able to get the system to accept the spreadsheet and it allows me to map everything correctly.

However, once I start the import I get an error for import users and import issues. This can be seen below. 
This is some of the warning messages that I get once it imports everything.

Then when I go over to the project, everything is there but the epics are separate from all the tasks.
