Jira portfolio - Start date of project calculated as 2/26/2000 Edited

[JulieM]

I had my plan exactly the way I needed it.  I calculated a start date of 2/12/18 and an end date of 8/13/18.  I reverted changes that were made and then hit calculate.  It changed my start date to 2/26/2000 and I can't figure out how to fix it.  Thought I would throw it out to the Community.

No response needed.  The sprint start date was entered wrong so it pulled into Jira wrong.
