100% Milestones Completion gone down to 25%

I also had this issue today. Was playing and all of my stats have reset. Was above 90 percent on milestones, now down to 28 percent. Most still have status bar full but they don't say completed although a few are missing completely. Arcade mode is at 0 along with Campaign Missions. WTF talk about irritating. I play on PC, Gamer Tag is -Sqrrl-Tag-, United States, noticed it around 9:00 am mountain time. March 25, 2019. Nvidia 1070.
