biometrical-journal problems

[saintland]

Dear Sir:
Thanks for creating the latex template for biometrical journal. I found two errors popped

1. when I specify leadauthor, the email trigger an error, "! Undefined control sequence. \mailto([email protected])
2. When I comment out the leadauthor part, a second error came out
   ! Undefined control sequence.
   l.57 \hypertarget
   {introduction}{%

You can see it the document body, % appears after \hypertarget before \section. Is it a pandoc 2 problem? Please give a look.
I run Rmd on Rstudio to generate tex and pdf files.

Thanks,

Han Sun

This error is solved adding the following line near top (line 8 for example) in the template (the same happens in other templates when using links):

\usepackage{hyperref}
