Should I worry about errors MozBot finds but is not on my sitemap?

[10JQKAs]

MozBot crawled a found a couple errors that isn't included on my sitemap plugin, such as duplicate page content on author pages.

Should I worry about things not on my sitemap?

Whether a page is or is not included in your sitemap is irrelevant. Search engines will perform a normal crawl of your site based on the navigation and links for your site. If any page on your site can be reached from any navigation or link on your site, then search engines can find it.

If the page is not marked with a noindex tag, then search engines may attempt to index the page which would cause a duplicate content issue.

A common cause of duplicate content issues on author pages is caused by a lack of information. An author who has provided a detailed bio produces a nice author page, but other authors may share the absolutely minimum amount of information required by your site to publish, and if there is no content other then a user name that would cause a duplicate content issue.

The preferable solution would be to gather more information from authors. Name, email, social accounts, location, areas of expertise, interests, credentials, etc. If you are unable to do such you can also noindex the pages for those authors.
