I'm not sure on how things work in the older version ( 1.03.1) but perhaps it's a timing thing. Are all your images taken from the same turn?
For instance, your first image clearly refers to the turn triggering the Czar event, so if your third image comes from the following turn then it's a fair chance that you're still equal to or below 75NM and therefore cop another hit. If your second image is from another turn - by which time you've managed to improve NM - then as you suggest you shouldn't be further penalised.
If that's not the case, then maybe you're seeing one of the bugs that was fixed in the 1.04 patch.
