The course navigation header is not functioning correctly.

The navigation header appears differently depending on whether you open a course from the "Learning" tab in the communities or click "Courses" in the 9-dot app library menu in the upper right corner.

It works correctly when clicking into the course from the 9-dot app library in the upper right corner. However, the navigation header is entirely different if you open the course from the "Learning" tab in the membership area.

The "Back" button should return to the module or lessons list when you are in a lesson. Instead, it goes back to the course library in the learning tab of the membership area, meaning you cannot navigate through the course modules and lessons. This is a critical bug that requires immediate attention.

The course library area also looks different depending on whether you open it from the membership "Learning" tab or the 9-dot app library "Courses" link. This should also be fixed to keep them the same.

The home and 9-dot app library buttons are also missing in the upper right corner of the navigation header, making it challenging to navigate the platform.

And the "Neue" course theme does not work on mobile when clicking from the "Learning" tab. Instead, it shows the New York theme.

🚨🐛 Please fix all these bugs as soon as possible.
