Hello everyone, I’m not sure whether this question belongs in Helix or Templates.

I have a problem with the menu in the Lt_eservice template — in my opinion (since it wasn’t checked during the update), the issue started after updating to Joomla 5.4. However, the Admin Tools for Joomla are also installed. When I deactivate them, the menu problem remains, which is why I assume it’s an update issue with Joomla 5.4. Installed Helix : 2.2.1

The menu now only works/displays as shown in the screenshot. What could be the cause of this problem, and how can it be resolved?
