I contacted support about this but I noticed the disclaimer saying they couldn't see individual notebooks, so I figured I might as well post here and see if anyone else has/had this issue.
I can't seem to get any data from Quandl's 10 year treasury dataset earlier than mid 2017, even though it's supposed to go back to 2002. Before it seemed like the factor was only working at random, but now it seems like its date related (well clearly is in the plot). Notebook attached.
