Can't find selector anymore. How can I find it/get it back to edit it?

Hi, I have re-allocated one selector to another parent selector. That selector was unfortunately one level below the selector itself and therefore it is not anymore connected to the "_root" directory (in the selector graph). Hence I can not find the re-allocated selector in the selector graph anymore nor can I find it anywhere else. How can I get a grip on it/find it to edit it? Thanks!

I found a solution myself: I exported the sitemap and corrected the parent directly in the script and imported it as a new sitemap. Now it works again.
