Orbit Around Selection doesn't work

Hi,
I don’t know if it’s me but I can’t orbit around selection in the viewport after selected an object even if it’s selected in the viewport options.
I follow the documentation here :https://docs.unrealengine.com/en-US/…ols/index.html

The issue happens with each project, even a new project.

I know that I have to press Alt to move around an object but I’d like it to be the default solution.
