This is really incomprehensibly strange. Adding separate citations makes the other citations look broken.
If I only have these two citations,
then the pdf result is perfectly normal.
But if I add either one of the two new citations,
then the pdf result shows "Autor" becomes "D. Autor"
Why does one citation affect other citations?
And I am using "Biblatex (natbib mode)" on Lyx. So far only this option works.





journal={The Quarterly journal of economics},is a real eye-sore. Please change it tojournal={The Quarterly Journal of Economics},. (Yes, I'm an economist too.) – Mico Sep 14 '20 at 01:26uniquename=false,anduniquelist=false,.
