Nightwave Plains of Eidolon Bounty

[Twiggs5]

I've completed 6 Plains of Eidolon bounties now, and my count for Nightwave is stuck at 4. My game is up to date, and I exited the Plains through the doorway to Cetus after each mission. I know that I completed them, because I got the mission rewards, and the achievement for completing 10 bounties on the Plains continued to count up after Nightwave stopped.
