The flagging history only shows your flags (with links/status) on Questions and Answers. Comment detail is left only as a count on the right-hand panel, but no links to those questions are provided.
Also, to relate to the answers/comments in one of your links, there may be a caching issue. Wait a bit to see if those counts do appear later.
This FAQThis FAQ and this onethis one don't directly answer your question, but it may be helpful to look at anyway.
I'm guessing, based on your update, that waiting it out did not clear up the problem? I don't have the answer to that directly, but perhaps you could seek out a particularly bad question or answer and flag it. If this changes the page, then it appears your hypothesis may be correct.
Are you aware if those comments still exist or have they been deleted? It may also be that you need a comment flag deemed helpful first, but that might be harder for you to track down.
