Hey ,
Thanks for pointing out the missing links. That page is populated manually and so we may have missed a few links.
The multiple Blueprint section issue you found is more of an illusion than reality. It’s most likely just the breadcrumbs at the top of the page missing a level in the hierarchy since there is truly only a single Blueprint section. Can you point out which page(s) have are missing the Unreal Editor Manual link in the breadcrumbs?
