We all saw that section of the Codex. It is a great idea, sort of a fishing thing, where you can see what was the smallest and the biggest one you "caught" so far. The problem is, it doesn't seem to work. It doesnt matter how many particular stars or planets you find the records sections will only contain a record of the first one you found even after you sell the exploration data. Is this a bug? It must be otherwise there is no point in that section at all.
