plugin showing on overview

[isleofwight]

I am adding following HTML code to Overview.tpl to display the formfiller template in the overview. But i get an error displayed on the overview screen:

</div>
<div class="admidio-overview-plugin col-sm-6 col-lg-4 col-xl-3" id="admidio-plugin-Formfiller">
<div class="card admidio-card">
<div class="card-body">
{load_admidio_plugin plugin="formfiller" file="formfiller.php"}
</div>
error shows as
The authorization check of the plugin failed. There is more than one menu item with the same URL defined.

=> /admidio/adm_program/overview.php

Note that formfiller.php operates correctly from the menu

The FormFiller plugin cannot be displayed on the overview page, it can only be started via a menu item.
