About a modded track that doesn't appear in the custom season list

Hey guys!

I downloaded a whole lot of aussie tracks from SCE to run a little V8 championship in AMS. It was all fine and dandy when I was creating the season with the custom season tool, but one track didn't appear in the list: the Hidden Valley (no pun intended). Someone knows how to fix it? (I know how to use the .scn and .gdb files, but I don't know what to change in this case, if there is something to change)
