Given that screenshot I suspect that this template is more to your liking. The "Goodreads:" in the identifier is redundant, given the column name. This template shows only the identifier value without the "goodreads:" prefix. It is also slightly faster.
Code:
program:
gr_id = select($identifiers, 'goodreads');
if gr_id then
l = urls_from_identifiers( 'goodreads:' & gr_id, '');
l = re(l, '>goodreads<', '>' & gr_id & '<')
else
l = ''
fi
