info chapter numbers {7,8} swapped

When viewing the haskell-mode info manual in emacs, chapters 7 and 8 have their numbers swapped. In the index node, this is the order of the 6th,7th and 8th entries:

• Indentation::
• Compilation::
• haskell-decl-scan-mode::

But when i navigate to "Compilation", I see "8 Compilation" instead of "7 Compilation" in the title. Likewise i see "7 `haskell-decl-scan-mode'" in the next node's title.
So either the numbers {7,8} are wrong, or the order of the index entries is.
