'Main' pve event progress reset bug

DeNappa

The current pve event contains a few fixed intro fights hat are playable once. Upon completion it is ticked off with a red check. However just now I returned to the event to see those fights 'unfought'. When I select them they give 0 points with full points in 65 days or so.
I.ve seen it in some previous event too, although I can't remember which one it was exactly. I regained access to the ongoing events after completing the intro fights again.
