I noticed this issue tonight and I'm not sure if it is a bug or not.
When you look at Banadin's author page https://storiesonline.net/a/Banadin there are two stories listed as being in the Ninth Grade 1958- 1959 universe.
But the stories have a (2) and a (3) implying that they are the 2nd and 3rd stories in a series.
When I look at the Ninth Grade 1958- 1959 universe page it only lists the two stories.
Why do they have a (2) and a (3) if there are only two stories in the series?
