plugins database doesn't contain all the library sections that exist all the server

I’m interested in potentially developing a utility to make my remote library management a little bit easier, so I’ve been digging into the structure of the database in the last few days. But when I “SELECT * FROM library_sections;” I see only three of the four libraries that my server. I tested that the server was working correctly, I was able to watch content from the missing library. For sanity’s sake, I also did “SELECT * FROM section_locations;” and that also was missing any reference to the fourth library.

Any help understanding where that data might be would be amazing!
