The Challenge Incursion Breaker I, II and III don't show correctly.
1. When you achieve II, it doesn't move up from I in the title of the achievement ... unlike some of the others that do work. This is also true after porting to a new zone. (I haven't checking logging out.)

2. When you hover over the 2nd option at the bottom, it's showing Challenge Incursion Break I - not III (which I assume should be the idea):

For reference, this is the 1st of the options at the bottom:

Playing on PC EU, Seasoned Difficulty, and collecting the achievements in order - Oblivion Portal was the one that should have triggered II (four items), and awarded 10 points.
