Does anyone know why I can't buy a return ticket between Thornton
Heath and Gatwick returning on a different date from when I start out?

For no more reason than, because you can't.

More specifically, because an open period return does not
exist for that journey (but TBH I don't think that tells you
any more than the first line that I wrote)
