How to fix this issue
Your dataset is missing the documentation-url column.
The Conservation area guidance explains how to fix the issue:
documentation-url
The URL of the webpage on your website that introduces the document.
Each document should be linked to from a documentation webpage that includes a short description of the data and the document you’re linking to. Each conservation area should have a unique URL. This means you can create a separate page for each one, or you could list several on one page. If you do that, there must be a separate anchor (fragment identifier) for each one. This means each section of your page should have its own URL. Most publishing systems will allow you to use a hashtag to create the identifiers for each conservation area you list - as in the examples shown.
Examples:
One conservation area per page: http://www.LPAwebsite.org.uk/conservationareas/smithroad
More than one conservation area per page with an anchor link for each one:
http://www.LPAwebsite.org.uk/conservationareas#smithroad
http://www.LPAwebsite.org.uk/conservationareas#broadhousepark
