Dear Orlando,
Thank you for reaching out. The menu issue after the Joomla 5.2.3 update may be due to module assignments or conflicts with your custom.css or template files. Try verifying the menu assignments and clearing caches.
Regarding the template version discrepancy, it’s best to update your copied template to match Helix Ultimate 2.1.1 while preserving your customizations in the custom.css file or overrides. This ensures compatibility with the latest Joomla version.
Joomla updates often modify core template files. Comparing the original and copied templates can help identify changes, and reapplying customizations may be necessary.
If you need further assistance, feel free to share access securely.
Best regards,
