That page is probably mostly meant to find candidate caches to fulfil challenges that require you to log caches that haven't been logged for a long time, so therefore it's natural that it shows caches you have neither created or logged.
If instead you want to see only your own caches you either need to create a custom filter that specifies yourself as the cache owner and use that (which is a function that is only available for paying members of Project-GC) or you can create a bookmark list of your own caches and specify to only show caches on that bookmark list.
