Last week Jim pointed out to me that the SEI_CONF state drop down had the incorrect states listed. There were states in there that were no longer in the code and haven't been for some time. This is a known issue (a href="https://git.ligo.org/cds/guardian/issues/6">GRD gitlab issue 6</a>), and the current solution is to restart the node. So I did. All better for now.
