Content Dimension Selector missing

Hi!

I’ve just installed Neos 2.0.x and setup the Neos Demo Site.
According to this screenshot in the neos.io newssection there should be some kind of dropdown to select the edited language, but i can’t find it.

Is there anything i need to enable / configure first?

Regards,
Florian

OK. At first I installed Neos by extracting the ZIP-file - Content Dimension Selector was missing.
Now I deleted everything and installed from composer - Content Dimension Selector is there.

Strange…
