1. Pretty much looks that way: I did get credit for the 40 waves (in arbitration); got the +5k standings hours before the swap. After the swap and completing the new eximus challenge, I have the same amount of standings so it appears that we lost the reward from the defense challenge (or the eximus challenge didn't increase the standings further). 2. Visual, at least for me: I did get credit for the Index so it appears to be a visual bug. I have screenshots to back it up (both 1. and 2. - of actual standings, not the notification during the mission) but I assume the loss of the reward for the defense challenge is intended until DE states otherwise.
