What is the issue?
Pages that have been specified as noindex / nofollow will not be indexed by Search Engines and therefore will not be found by your potential website visitors in Search results. This should only be intentional if you do not wish for the document to be accessed by search engine users, e.g. a logged-in page or outdated content.
How to fix
If the page is relevant to be ranking in the search results, update the meta robots directive to index, follow. This can be found in the header of your page. If you don't have access to your website's frontend, ask your developer to make this change for you. The header robots tag in the report refers to the HTTP header - this is set to noindex only if actively specified. Learn more about this here.
