It's more that it's not clear from the update notes because I didn't take PvP into account, but party 1 (your party in PvE) will be blue, and party 2 (enemy party in PvE) will be purple. Who is party 1 and who is party 2 is determined by who starts the fight in PvP. But this isn't a bug from what's being described.
