Hey MariusG,
Thank you for the reply! I do have a caching plugin but have cleared the cache and that did not resolve the issue.
What’s weird is this issue in Search Console showed up Sept 7th but the sitemap is showing the page was last modified in Jan 2017. So strikes me as strange that this page shows up in the sitemap almost three years later.
Is there any easy way for me to PM you the sitemap URL? prefer to not post URLs publicly.
