Welcome to the Q&A Forum

After a bit more digging (and a venture down a character encoding rabbit hole) I haven't come up with any smoking guns (mixed metaphor alert). I don't suppose there's any chance those pages could have had a noarchive meta tag on them (or nosnippet) at any point in the past is there? It's possible that would remove the link but not remove the cached copy itself. I'm honestly not sure there is going to be a ton of ROI to going further down the rabbit hole to be honest. I think it's most likely to either remain unsolved or be something you can't do anything about (and we don't even know if it's really causing actual issues). If you want to continue debugging, I would run through these steps: Take a page like the one you mentioned and duplicate it on a different URL outside of that folder structure and see if that gets a cache link If it does, try 301 redirecting the page without the cache link to the one with the cache link and see if it disappears Try the above but with the redirect the other way around This will help narrow down what's going on - but doesn't guarantee that it'll be fixable, nor that there is actually any value to getting the cache link back. If you have any more evidence on the other issues you referred to (featured snippets etc) let me know and I can look at that separately. Let me know if you dig anything out. Good luck.
