Special:Badtitle/NS90:Forum:Tech Wishlist And Bug Reports/Level 1 headers are broken/reply

Note: edited your post to fix that link.

As for the busted headers, that's normal. For one, level one headers are the page title in MW, level two are == Title == sections, Level 3 the === Title === sections, and so forth.

What you are seeing is MW's confusion at the improper use of header levels.
