Considering what was revealed in the latest chapter, Ddraig and Albion didn't fight for any real reason. They just fought because they wanted to challenge each other. And I think Ddraig and Albion saying that they can't remember the reason they were fighting was either a lie on their part, or Ishibumi was serious about them not remembering, and just recently came up with this little plot twist.
