Not working

Hello there, just updated to the latest version hoping it would work, but it still aint working..

I have used the shortcode [staff_list] like it says in the description here on WS. That shortcode wont work at all, it just prints [staff_list] on the post/page.

With the other shortcode [simple-staff-list] that’s on the ‘usage’ page in the admin area it als wont work, but when i look at the code it shows the plugin is being loaded.. it only wont show any staffmembers..

<div class="staff-member-listing"><div class="staff-member even"></div> <!-- Close staff-member --><div class="staff-member odd"></div> <!-- Close staff-member --></div>
