Indeed, earlier, I had tried to simplify the verbage for you. "unreconciled" more accurately is "no Recon object created - we might have had an error in the backend of OpenRefine, or the reconcile service you are using might have had an error (like HTTP 504 gateway timeout) or we couldn't properly parse it's response because it's malformed somehow"
If you are using Wikidata service to reconcile, it might have been that reconciling that cell "LORD AND TAYLOR" had an error, or no response back from the server. Hard to tell.
You could click on the Flag for that row, then facet only by Flag and do a GREL expression preview with something like:
cell.recon
to see if there is even a [object Recon] that was created by our backend code.
If you wanted further, you could create a new column based on the reconciled "who_reconciliation" column and do something like:
cell.recon.candidates
which should preview the candidates object to see if one was even created and if not, then it will show "null" in light grey. This "null" might be do to a backend error with the server and it did not return any candidates, or had a more severe HTTP 500+ error which are not shown or stored currently. (unfortunately)
The above shows my test with a bit of your same record data where I did get a match for "LORD AND TAYLOR".
Below, in the reconcile settings, I clicked the radio button for "Reconcile against no particular type" and "Auto-match candidates with high confidence"
Here's the test project you can import and experiment with if needed (attached)
