Maybe I misunderstood…
Best I can tell the bio is shorter than the excerpt length so it only appears to be the same.
Create a much longer bio and you’ll see that only an excerpt is shown until you click the read more link.
By default, the template only shows the bio, nothing more. If you want more to be displayed, you need to configure the template via its shortcode options to turn on additional details. Here’s the lis of options you can turn back on:
enable_bio=TRUE enable_bio_head=FALSE enable_note=FALSE enable_note_head=FALSE show_title=FALSE show_org=FALSE show_contact_name=FALSE show_family=FALSE show_addresses=FALSE show_phone_numbers=FALSE show_email=FALSE show_im=FALSE show_social_media=FALSE show_dates=FALSE show_links=FALSE
The complete list of options and a summary on how to use them can be found here.
Hopefully I understood correctly and answered your question this time.
