Why is "Save into package" not showing all my packages?

I recently installed a new version of the Pipeline Pilot server (21.2), and I apparently didn't fully migrate all my configuration from my old world server. I have a custom package that's installed and which I can see through "pkgutil -l", but I can't see that package in the client UI's "save into package" list when I want to save my protocol directly into that package. I see that I have the "EditAnyPackage" permission, and I have vague distant memories that that should be enough to accomplish this, but apparently not. I also have made sure that I restarted my server and client app just in case there's some caching going on. I still don't see my package here. What do I need to set up so that I can see my own packages in this list?
