combining La croisade noire du Jedi fou

I keep combining La croisade noire du Jedi fou with Star Wars: Thrawn Trilogy, and it keeps coming back. Is someone remaking it? Or is this some kind of bug?

If you look at the edit history, you'll see that there is a running line of yellow each time you combine it.
There seems to be a bug, which I think is a known bug but I can't remember how it was entered.

ETA: Found the bug:

I think this has been fixed now.
