JA Moviemax Gallery problem

Hi,
I have installed "JA Moviemax for Joomla 4 - quickstart" on my local pc and the Gallery have 2 problem:

if I click con the icon of article to see gallery the semi-dark screen opens but no image are visible
the second problem is the wrong display of the icon on an article (I attach image)

Same problem in both php 8.1 and 7.4

The only error I see on Chrome console is:
Failed to load resource: the server responded with a status of 404 (Not Found) on file system.css:1

Can you help me?
Thank you

It seems to be issue in Joomla 4, I've reported to our team to get it fixed. Kindly wait.

UPDATE:

You can backup these files:

ROOT/templates/ja_moviemax/less/joomla.less
ROOT/templates/ja_moviemax/css/template.css

and update with attached file (unzip first)

fix-moviemax.zip

About the 404 error for system.css file, Joomla 4 removed this file so it notices that message. You can open this file:

ROOT/templates/ja_moviemax/tpls/blocks/head.php

and remove line from 35-38:

<?php
// SYSTEM CSS
$this->addStyleSheet(JURI::base(true) . '/templates/system/css/system.css');
?>

Thanks a lot, the fix works
