if i go directly to this link (try opening in a new private browsing session), i do get results:
interestingly, at least some of these observations come from outside of Florida. it looks like the screen is effectively ignoring the place filter.
if i change the Quality Grade filter to Research, the photos all go away. interestingly, if i refresh the browser window, i get everything back again.
if i clear the Florida filter and manually reapply it, then i can’t reproduce the steps above. but then if i clear the Florida filter, i can go directly to that link again and get the same results as before.
there’s something strange with the screen beyond the behavior that was originally reported in the original post.
