Thanks for the link.
For the venue to show in the mini calendar you have to add some coding to the template.
To do that follow our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
to move and edit this template in your theme:
events-calendar-pro\views\pro\widgets\modules\single-event.php
Then on that template you will need to add this coding:

Below this markup:
<div class=”vcard adr location”>
That showed the venue link and name for me, let me know if you see something different.
Thanks
