JUX Portfolio - not working

Hello - yesterday I bought JUX Portfolio - Responsive Joomla Extension because I like this module very much.
I use Joomla 4.1. & php8 .
The installation & editing are very easy to understand and I have in the backend at the moment 9 images (test posts) ready which are linked.
On the website as set in the settings (at the moment) 3 posts are displayed.

But unfortunately "Load More" does not work, so that more images are not displayed.
The menu bar above the images is displayed, but, if I want to click on the different bouten to sort, that unfortunately also does not work - I would be very happy about help, because I find this module very nice.

danke - an was für eine adresse soll ich die daten senden?
