Are hints.md files rendering properly?
Here are the hints I see at https://exercism.org/tracks/haskell/exercises/lucians-luscious-lasagna/edit:

As you can see, I can see a heading, "General", and two links: "Declaring modules", and "Indentation rules".
This does not seem to match the content at https://github.com/exercism/haskell/blob/main/exercises/concept/lucians-luscious-lasagna/.docs/hints.md. There I see two headings: "General" and "Modules and Indentation". The second one is missing.
Text under General, with a sentence beginning with "Basic numbers operators are described"... is also missing.
The hints for Lucians Luscious Lasagna at the Rust track do render properly: source, rendering.
I guess a syntax issue. Ours does not start with # Hints and uses only level-1 headers.
Relevant docs: for practice exercises, and more extensively for concept exercises.
