Is it possible to have more than 1 Folder in a nested structure, e.g.

Series A
...Season 1
......part1.rar
......part2.rar
...Season 2
......part1.rar
Series B
...Season 1
...

Whenever I try to move Season1 in a new Folder, it becomes the folder.
I'm pretty sure this once worked. I need no plugin-magic, would do sorting and naming by myself.
