Why is the Haddock documentation not showing up on Hackage?

I've got a package on Hackage that has haddock generated documentation but it isn't showing up on the Hackage page. I'm able to upload everything successfully but the documentation doesn't show up.

I generate the documentation with cabal haddock or with Package > Build Documentation in the Leksah IDE.

When I go to Package > Open Doc in Leksah, it can't find it because it's looking for dist/doc/html/hspec/hspec/index.html but the generated file is at dist/doc/html/hspec/index.html. I assume that Hackage is also looking in the same place.

I'm guessing that my source files aren't in the expected places, but I don't know how else they should be.

The source and directory structure can be found at https://github.com/trystan/hspec.
