Problem with "et al" citations

[stefan11]

There is a problem with "et. al." It shows two authors instead of one + "et. al.". This has strange consequences since Bouma, Malouf, et. al. is actually longer than the full citation "Bouma, Malouf & Sag":

English GT and Chinese GT are both affected.

I guess some biblatex configuration in the class can fix this.

why is the first one printed with three names? Can you please paste a MWE.

[stefan11]

I used \citep* to get all names.

[stefan11]

I found the reason. It is a feature, not a bug. There would be two identical Bouma et al. (2001), so it takes an unambiguous prefix. However, the outcome is longer than a full citation would be. Maybe I should file a bug report with biblatex/biber.

Some languages show extraction path marking \citep*{BMS2001a}. \citet{BMS2001a} give a lot of
examples. And there is also \citet*{BvNM2001a}. They wrote about a lot of important things \citep{BvNM2001a}.
