[Plugin: Organize Series] wp_seriesmeta_write(); Output issue

When I use
echo wp_seriesmeta_write();
in my template file, it outputs the meta information, but below the meta information it also outputs %postcontent%.

I see that this is a token in the code, but it should not display on the front end?

Using version 2.4.1

Thanks much
