I figured it out like 5 minutes after my post. The problem was singling out the ones that had a "-". Searching for that character didn't work. It must be a search syntax character or something (like the "-" on the Google search engine).
Anyway, I don't know what is causing this rendering problem, but I am working on an API that should serve as a temporary fix by making the BGO itself smaller. It will also allow you to make custom BGOs bigger
than the originals, and change their render priority.
