Your total as of this writing is 23 duplicate logs (OK, one triplicate). Why is it a problem to get all that on one page?
The cache ID for each entry links to one of the duplicate logs. The latest one, I think. Note that they may not necessarily be duplicates as such. See for instance the first cache in your list; there the same cacher has logged the cache twice in different years, apparently not knowing about the first log on the second visit.
