There's probably a reason for this...

Today is Thursday, 8 September 2016. I'm looking at the FRED series CMDEBT. Just above the graph, to the left, it tells me the value of the most recent data item (Q1 2016: 14,316.00) and when the series was last updated: Jun 9, 2016. That all makes sense.

Now, down below the graph are the Notes, and among the notes the Suggested Citation. And the citation ends thus:

... [CMDEBT], retrieved from FRED, Federal Reserve Bank of St. Louis;
https://fred.stlouisfed.org/series/CMDEBT, August 22, 2016.

Where the hell did August 22 come from? This is Thursday, 8 September. The graph was updated on 9 June.

August 22?
