I have noticed that several of the Minifigures added recently to the catalog do not seem to relate to the set they were created from.
The "Comes In" tab do not show up and the Minifigs do not appear in the sets (ex: "Martian Manhunter", "Superman, Blue Suit and Soft Cape ", "Chancellor Palpatine",....).

So, it's possible you may have caught the minifigs halfway between these two steps. Either that or no one has submitted the inventory changes yet.
How to submit the next step (associating the fig in the set) ?
Add the minifig and remove the parts that the minifig is made of, then submit.
Note that it can take 1-2 days for the submission to be approved.
