[Az-Geocaching] Another searching question

Been lurking for awhile, so thought I'd throw out another question, though
I'm afraid I already know the answer.

I'm trying to use the geocaching.com map feature (visualize waypoints) to
just show those caches I have not yet found. So, I get the listing of these
caches, click on the Map It icon to get the map. However, my finds are
listed. I uncheck the box below that says 'List Caches you found', refresh
the page, but they're still there! (Checkbox doesn't seem to work?) Tried
through a PQ, but there's no option to map the results provided.

Is my only option to convert my .gpx file into a Streets & Trips file, for
example, and go that route (no pun intended)?

Thanks,
David
