Missing property nodes for preds in go basic

There appear to be some pred definitions in go basic that don't have corresponding property nodes. I believe there were also some val values that were missing property nodes as well that Seth found - IAO_0000277 I think? That could be wrong though.

go-basic was downloaded from obo foundry a few hours ago.
