knb=> select archived, obsoleted_by from systemmetadata where guid='nikkis.27.1';
archived | obsoleted_by
----------+--------------
f |
(1 row)

This means the guid nikkis.27.1 is not archived.

However,

knb=> select guid, obsoletes from systemmetadata where obsoletes='nikkis.27.1';
guid | obsoletes
-------------+-------------
nikkis.27.5 | nikkis.27.1
(1 row)

This means that the nikkis.27.1 is archived.

Those guids with the issues are:
peggym.36.15
judithk.1014.1
judithk.1018.2
judithk.1000.10
peggym.82.4
peggym.1048.6
nikkis.7.2
judithk.1034.1
nikkis.169.2
judithk.332.1
nikkis.27.1

In them n-demo-4, there are three ids with the issue:
doi:10.5072/FK2/LTER/knb-lter-gce.333.5
doi:10.5072/FK2/LTER/knb-lter-gce.331.12
doi:10.5072/FK2/LTER/knb-lter-gce.335.6

We need to figure out why this happened.
