You are 100% right. My fault. It wasn't originally "originCommunity", it was more current community, and when I did the rename I wasn't careful. I need to add a new field for that. I apologize and have created an issue to start the process of getting these and others fixed (https://github.com/breck7/pldb/issues/145)
Makes me suspicious of this - it's probably not deeply researched or considered.
