I don't think you can "fix" it anyway. I had the same problem about two or three months ago, and mentioned it in "We are listening to your feedback". Someone (not a blue) told me that it happens every once in a while. It seems like when it gets to some magic number of threads displayed there, it just dumps everything that would come after "Show more" and starts that list from scratch. My own "Topics participated in" list is starting to get pretty long again, so I guess I'll just wait and see if it "resets" again.
